Session Notes — v9 Cross-Tradition Investigation

Date: 2026-02-13 → 2026-02-14 (continued)

Overview

Searched medieval Sri Lankan and South Indian pharmaceutical traditions for external attestation of H12-decoded Voynich vocabulary, especially the "state-marker" paradigm. Then pivoted to corpus linguistics: downloaded 55M-char Sinhala corpus (Tipitaka), compared grammar/vocabulary patterns, and analyzed specific folio structures.

1. SEMANTIC COVERAGE ANALYSIS (Pre-Investigation)

Level Tokens %
CONFIRMED (locked meanings) 11,245 30.4%
PLAUSIBLE (reasonable, unverified) 10,893 29.4%
PARTIAL (one component known) 9,087 24.5%
PROPOSED (unverified) 2,818 7.6%
Dictionary match, no meaning 864 2.3%
Completely opaque 1,849 5.0%
Noise/artifacts 268 0.7%

Strict reading: 30.4%. With plausible: 59.8%. Any meaning: 91.9%.

2. F85V2 ROSETTE FOLDOUT — DECODED

  • 347 words, 82.1% glossed
  • Pharmaceutical vocabulary throughout (uteda, ugala, ula, ala)
  • ugara (throat) 7× — possible throat-preparation section
  • Saved: Paper/data/f85v2_rosette_decoded.tsv

3. TIER 2 VOCABULARY INTEGRATION

  • 45 entries added to decoded_vocabulary.tsv
  • Clearly marked: tier column, TIER2_HIGH/TIER2_MEDIUM confidence, "TIER2 PROPOSED:" notes
  • Combined coverage: 95.1% → 97.7% (+2.54%)

4. CARTER'S DICTIONARY (1924) — KEY FINDINGS

Confirmed pharmaceutical entries:

  • gediya (ගෙඩිය): "fruit; bulb; boil, tumour, lump, knot" + "snake poison"
  • a gadaya (අ ගදය): "drug, medicine" (Sinhala: beheta) — gada root = medicine
  • teda (තෙද): Elu form of tejaya = "fire, heat, pungency"
  • tejo-dhatuva: "element of fire; bodily heat and digestive power"
  • meda (මෙද): "marrow, fat" AND "a drug, one of the 8 principal medicaments" (ashtavarga)
  • sedaya (සේදය): "warmth, heat, perspiration" (< Skt sveda = sudation)
  • gala (ගල): "stone, rock" + "(Sans) throat" — dual meaning confirmed
  • garanavā (ගරනවා): "to sift, riddle, screen sand; cleanse grain" — sifting verb
  • garada (ගරද): "poisoning, poisonous, unwholesome"
  • garaya (ගරය): "sickness, poison, antidote"
  • ūla (ඌල): "fountain, spring of water" — exact match
  • leḍa (ලෙඩ): "illness, disease" — standard Sinhala disease term
  • ugura (උගුර): "throat, gorge"

Revised state-marker assessment:

  • teda: ATTESTED — Elu fire/heat/pungency (decoction = heat process)
  • geda: CONNECTED — gadaya = drug/medicine; gediya = fruit/lump
  • seda: ATTESTED — warmth/heat/perspiration (sudation therapy)
  • meda: CONFIRMED — fat + named medicinal (ashtavarga)
  • keda: Carter's says "weariness, fatigue" — USER INSIGHT: fatigue IS a symptom/condition in Ayurveda

5. BHESAJJAMANJUSA (13th c. Pali) — CRITICAL EXTERNAL ATTESTATION

PDF obtained: Paper/references/bhesajjamanjusa.pdf (45.9MB)

Text extracted: 27,867 lines

Key vocabulary matches found:

  1. "Seda meda visosano" — seda + meda paired in pharmaceutical formula (desiccation of sweat + fat)
  2. "Meda seda visosano" — same pair reversed, appears 3 times
  3. "dve meda (mahamevan, sulumevan)" — "two medas" WITH SINHALA PLANT NAMES
  4. "maha-sedam" = great steam bath (sudation therapy)
  5. "sedetum" = infinitive "to cause sweating"
  6. "Snehano sedano tikkho" — "oleating, sweat-inducing, sharp" (pharmaceutical properties)
  7. "Kapha meda gala amaye" — THREE decoded terms in one line (phlegm + fat + throat + disease)
  8. "thula mulani" — coarse roots (both decoded terms together)
  9. "usnam sula-haram" — "hot, pain-removing" (pharmaceutical property)
  10. "Gulma-sula" — abdominal mass pain (disease category)
  11. "gula = molasses" — confirmed as pill-binder; "gulani" = pills (plural)
  12. "Mulam sadhu virecanam" — "root is good as purgative"
  13. "Garaya" — poison/sickness; "Una-Gara" = disease demon

Structural parallel:

Bhesajjamanjusa chapters organized by drug vehicle (Toyavagga=water, Madhuvagga=honey, Telavagga=oils) match decoded Voynich's organization by state-markers.

6. CROSS-TRADITION FINDINGS

Kerala Ayurveda:

  • Sahasrayogam chapter structure (Kashaya/Ghrita/Taila/Churna) maps to decoded state-markers
  • Kerala has 28 Visha Vaidya centers for gara (compound poison) treatment
  • Sanskrit meda dhatu = fat tissue, core Ayurvedic concept

Tamil Siddha:

  • NEGATIVE finding strengthens Sinhala ID: every verifiable term matches Sinhala/Pali, not Tamil
  • Tamil uses different vocabulary for same concepts (vadi not gala, tontai not ugara)
  • Shared vocabulary comes through Sanskrit substratum only

Medieval Sinhala texts identified:

  1. Sarartha Sangrahaya (4th c.) — earliest Sri Lankan medical text
  2. Bhesajjamanjusa (13th c.) — only Pali medical text, now in our references
  3. Yogaratnakaraya (15th c.) — first Sinhala medical textbook
  4. Vatika Prakaranaya (1879) — 5,293 verses on pills and pastes
  5. Vanavasa Nighanduva — Kandyan pharmaceutical plant glossary

Morphological patterns confirmed:

  • Past-participial -la suffix: kakala (having boiled), viyala (having dried) — from Bodleian MSS
  • u- prefix productive: ugura, ugena, udara all attested

7. SEARCHABLE DIGITAL RESOURCES IDENTIFIED

  1. SOAS Bhesajjamanjusa critical edition — NOW IN OUR REFERENCES

kurundu (cinnamon) tacam (bark) INDIRECT 3624, 5829
karabu (clove) karabhim(?) UNCERTAIN 6215

Key note: "buluki" (line 5158) is a Pali-ized form of Sinhala "bulu" — shows the author borrowed directly from Sinhala rather than using purely Sanskrit-derived Pali forms.

9. BHESAJJAMANJUSA — SINHALA COMMENTARY SECTIONS

Language-switching documented:

  • Line 14170: "It has been up to the present point carried on in Sinhalese, but now the commentator begins to give his explanations in Pali."
  • Line 14393: "The passages are long and are interlaced with Sinhalese passages."
  • Line 16067: "The Sinhalese paraphrase explains it as 'sau-varci-ksaro'."

Sinhala plant names glossing Pali terms:

Pali Group Sinhala Names
balattayam (3 bala plants) kotikan-bewila, mahabewila, siriwedi bewila
dve meda (2 meda plants) mahamevan, sulumevan
catupannikam (4 panni) asvenna, pusvenna, masvenna, munvenna
jivakosabhamo div, osabiya
saha sulu, maha, geladi
vira kavelau / bimpusula
kalinga komadu (hill-grown gourd)
alabu lapu (bottle gourd)
madhuka Mee (Sinhalese), Illuppai (Tamil)
panasa Kos (Sinhalese jackfruit)

Critical body-term gloss (line 16064):

passora-gala-roga-ari = "destroyer of diseases of sides, throat"

  • passa (sides) = Sinhala for Sanskrit hrt
  • ura (chest) = Sinhala
  • gala (throat) = same in Pali and Sinhala

Decoded Voynich terms matched: 10/13

meda (13×), gula (2×), sula (4×), mula (multiple), gala (multiple), gara (4×), sara (2×), kala (3×), thula (1×), seda (multiple). NOT found: leda, ula (standalone), mea — all Sinhala-specific forms.

10. BHESAJJAMANJUSA — THESIS STRUCTURE (No Standalone Glossary)

Part IV Notes (lines 13950-16660) contains the "unlisted Pali scientific terms":

  • 30+ botanical identifications with Latin/Sinhala/Hindi/Tamil names
  • Verse-by-verse commentary with Sinhala paraphrase explanations
  • Comparative section (Siddhasara vs Bhesajjamanjusa) from line 15599
  • Part V Essay (lines 16660-27430) catalogs 49 medical manuscripts including:
    • Behet Patuna: "index of medicines in Sinhalese and Sanskrit" (BM Or. 6612.109)
    • Saraswathie Bighanduwa: "dictionary of medical material in Sanskrit and Sinhalese"
    • Sri Vasudeva Nighanduwa: "Sanskrit slokas with Sinhalese and Tamil synonyms"

11. KEDA/KLEDA — BREAKTHROUGH: l-DELETION PATHWAY DOCUMENTED

The Myanmar Pali Abhidhana dictionary explicitly states:

kedāra [Kleda(klida)+āra] ... "lalopo" (l-deletion) ... kledīyatīti kedāraṃ

Translation: "kleda → keda" via deletion of l (lalopo), producing kedāra = "wet field/paddy field"

Supporting evidence:

  1. kledanam found in Bhesajjamanjusa line 6024: "Saraudclam kledanam guru" = "moistening, heavy" — a formal drug property classification
  2. kleda in Ayurveda = moisture/dampness; pathological excess = disease factor
  3. Kledaka Kapha = one of 5 Kapha subtypes (stomach moistening for digestion)
  4. Sanskrit Apte dictionary: kleda = "wetness, moisture, dampness; discharge from a sore"

Revised state-marker paradigm — ALL 5 NOW PHARMACEUTICAL:

Marker Etymology Meaning Status
teda < Skt tejas via Elu tejaya fire/heat/pungency ATTESTED
seda < Skt sveda sweat/heat/perspiration ATTESTED
meda < Skt medas fat/marrow + named medicament CONFIRMED
geda ← gadaya/gediya drug/medicine; fruit/lump CONNECTED
keda < Skt kleda via lalopo moisture/dampness/wet-state NEWLY ATTESTED

The keda = kleda pathway is not a reconstruction — it is a documented Pali grammatical rule cited in the Dhānapada-ṭīkā (verse 447).

12. CLOUGH'S DICTIONARY (1892) — ADDITIONAL FINDINGS

Term Clough Entry Significance
keda "mark, sign" NEW meaning (Carter had "weariness")
Me'dd "drug, root resembling ginger; one of 8 principal medicaments; cooling, emollient; fever/consumption" Richer than Carter
Gediya "fruit; boil, tumour" — dozens of plant compounds Core botanical term
Se'da "silk; sweat, perspiration; heat, warmth" (Pali < sveda) Confirmed
Ugura "throat" (pl. uguru) Confirmed (note: ugura not ugara)
Garanawd "to cleanse grain, separate from dirt, to sift" Exact match
Teja "power, fire, heat, pungency" teda NOT a headword; teja is standard
kleda NOT FOUND as Sinhala headword —
ugeda/uteda/gameda NOT FOUND Compounds not lexicalized

13. BHESAJJAMANJUSA PART V — 49 MANUSCRIPT CATALOG

Pharmaceutical Formularies:

  • Guli Kalka Kaviliya — "preparing guli (pills) and kalka (pastes)" — matches decoded gula
  • Taila Vidhiya — "preparation of medicinal oils" (88 slokas)
  • Vaidyalankaya — herb gathering, drug compounding, decoctions/oils, auspicious times
  • Vaidyama Samgraha — "purifying metals and substances for medicinal preparations"

Drug Dictionaries:

  • Nava Jatiya Niganduwa — "obsolete Sinhalese words with Sanskrit equivalents," ~600 yrs, BM Or.6612.75
  • Vanavasa Nighanduwa — ONLY dict including Pali alongside Sanskrit/Tamil→Sinhala
  • Sara Niganduwa — dated 1265 AD, compiled by monk at Dambulla
  • Siddha Usada Bighanduwa — "widely used by medical students," printed edition
  • Birimal Nighanduwa — drug dict in Sinhala verse, dated 1748

Key Terminology:

  • wattoru-pot = "manuals of prescriptions" (standard format name)
  • behet = medicines (Behet Patuna = "index of medicines")
  • guli = pills, kalka = pastes
  • Sveda-vidhi = sudation method (Yogaratnakaraya ch.44)
  • Medical knowledge as "family heirlooms" in specialist families
  • All MSS in BM Nevill Collection: Or. 6612.xxx

HIGHEST PRIORITY LEAD:

Nava Jatiya Niganduwa (BM Or. 6612.75) — ~600yr old glossary of "obsolete Sinhalese" pharmaceutical terms. If it contains keda/geda/teda/seda/meda, definitive evidence for the state-marker paradigm.

15. CCRAS / EXTERNAL ATTESTATION — FINAL RESULTS

CCRAS portal was down (Indian gov server). Used Sanskrit dictionaries + Charaka Samhita Online instead.

The Kleda-Sveda-Meda Triad (Classical Ayurveda):

  • Sveda (sweat) = waste product (mala) of meda dhatu (fat) metabolism
  • Sveda maintains kleda (moisture) balance
  • Sweat channels (swedavaha srotas) originate from meda dhatu
  • 3 of 5 state-markers form a documented Ayurvedic physiological system

Gala — Etymological Double Meaning:

Sanskrit root GAL = "to drop, to distil." Causative galaya:

  • "to percolate" (Dashakamacharita 156.2)
  • "to sift" (Sushruta 1.165.18)
  • "to dilute" (Sushruta 1.166.6) Throat + filtering share the same root — not mere homophony.

Gara — Charaka Chikitsa Sthana 23, verse 14:

"Gara visha is prepared artificially by combination of various substances. It produces various diseases." Third poison category alongside plant + animal.

Attestation confirmed for: kleda/kledana (Benfey, Sushruta 1.76.19), gala (Shabda Sagara,

Sushruta), gara (Shabda Sagara, Charaka), meda (Shabda Sagara + Plant Names Dict — 5 species), teja (Shabda Sagara), sveda (Shabda Sagara, Charaka Sharira 7/15), leda (Sinhala dictionaries). NOT found: ugeda, uteda, gameda, ula (water meaning), ugara.

17. JAYAWEERA PLANT NAME SEARCH — RESULTS

All 5 parts of Jayaweera's "Medicinal Plants Used in Ceylon" (625 species, 48,190 lines) downloaded and searched systematically against 16 decoded plant names.

Confirmed (12/16):

Decoded Jayaweera Match Species Notes
aralu Aralu, Terminalia Terminalia chebula Triphala member; "greatly valued"
bulu Bulu, Terminalia Terminalia bellirica Triphala member
nelli Nelli, Phyllanthus Phyllanthus emblica Triphala member
ata/attana Attana, Datura Datura metel "Large Thorn-apple" — spiny capsules
mara Mara, Solanum/Cissampelos Solanum nigrum / C. pareira Nightshade family confirmed
kera Kekiri/Pipinja Cucumis sativus Multiple cucumber species listed
sarala Sarala, Pinus Pinus spp. Pine resin medicinal
tamala Tamalapatra Cinnamomum tamala = Cinnamomum synonym, cinnamon leaf
thula Sthula churna (processing term) "Coarse powder" — not a plant name
gula Gulika/Gutika (dosage form) "Pill" — confirmed pharmaceutical
mula Mula (root general) Universal Ayurvedic term
pudina Pudina Mentha spp. NOT Sinhala — Sanskrit/Tamil/Hindi loan

Corrections:

  1. tadala = Taro (Colocasia), NOT Palmyra Palm

    • Jayaweera: "Tala, Tala-goya" = Cyperus rotundus (nut-grass)
    • "Tal-ala" = taro tuber (Colocasia esculenta)
    • Palmyra Palm (Borassus) Sinhala name = "Tal" not "tadala"
    • Previous identification was WRONG — needs correction

  2. pudina is NOT Sinhala — Sanskrit/Tamil/Hindi borrowing; no Elu form

    • Genuine Sinhala for mint would be different
    • Weakens f14r identification but doesn't invalidate it

  3. amu = Kodo millet (Paspalum scrobiculatum) — NEW identification

    • Jayaweera: Amu = Paspalum scrobiculatum (Kodo millet)
    • Currently unidentified in decoded_vocabulary.tsv (3 tokens, EVA ysho)
    • Grain used in traditional medicine

Not Found (4/16):

  • olea (olive) — no matching Sinhala name in Jayaweera
  • talasa (date-palm variant) — not directly matched
  • rameda — pharmaceutical compound, not a plant
  • ugeda — processing state, not a plant

New Potential Identifications:

  • thala (7 tokens, EVA cthal): Could be Sesamum indicum (sesame)
    • Jayaweera: "Thala" = sesame, one of most important oil plants
    • Currently glossed as "place/put" compound — needs contextual check
    • f70r2 (zodiac) has "tala" — unlikely to be sesame there
    • VERDICT: Possible but requires folio-by-folio context analysis

19. MANCHESTER PALM-LEAF MANUSCRIPTS — DEAD END

All 32 digitized manuscripts at Manchester/Rylands are Buddhist canonical texts (Tipitaka/commentaries). None are medical or pharmaceutical. The 21 palm-leaf manuscripts donated by T.W. Rhys Davids in 1915 are exclusively Pali scriptural texts. ~40 un-digitized manuscripts remain — medical content possible but unknown. Catalog: Jayawickrama 1972 (not online).

UK Sinhalese medical MSS are at Bodleian (Oxford) and British Library (London):

  • Bodleian MS Sansk.c.123(R): Yogamuktavali-samgraha — formulary organized by prep type (peya, modaka, leha, curna, kalka, gutika/guli, taila, ghrta, nasya, anjana, kvatha, sveda, dhupa, pralepa)
  • Bodleian MS Sansk.c.125(R): Vaidyalankara-samgraha + Bhesajjamanjusa fragment
  • Bodleian MS Sinh.d.5(R): Tailavidhiya — Sinhala manual on medicinal oil preparation
  • Bodleian MS Sinh.d.3(R): 49+ diseases with pharmaceutical recipes
  • BL Or. 4142: Yogaratnakara — 457 folios, 49 chapters, ends with Vishnu-raja-guliya pill
  • BL: Vattorupota (Behet-vattoru-pot) — physician's formulary carried in practice
  • Royal College of Physicians: Vattoru-pota (early 19th c. palm-leaf)

20. CHANDRASENA — CHEMISTRY & PHARMACOLOGY OF CEYLON MEDICINAL PLANTS

Accessed on Archive.org: https://archive.org/details/dli.ernet.8078 Full OCR text downloaded (14,050 lines, 88.77% OCR confidence).

Confirmed plant names:

Term Match Details
aralu YES Terminalia chebula, p.102 — Triphala member
bulu YES Terminalia bellerica, p.101 — Triphala member, kernel narcotic
mara YES In compound "Sooriya-mara" = Albina odoratissima (large tree)
tamala YES Index entry p.85 (cross-ref in Melia section)
gara YES In compounds "Patala-garadu", "Hamasagara" — poison-related names
mula YES "Pancha Mula" (five-root preparation) — key Ayurvedic formulation
ata PARTIAL "Aththa" for Anona muricata (Katu Aththa) and A. reticulata (Wali Aththa)

Not found: nelli, kera, sarala, tadala, pudina, amu, thala, gala, meda, seda, teda, keda, gula

Book uses English for preparation terms ("decoction" 75×, "oil", "pellets") not Sinhala/Sanskrit.

21. TADALA — MORPHOLOGICAL ANALYSIS

Three possible analyses for the plant label on f9r:

Analysis Meaning Evidence
ta + dala "that petal/leaf" Sinhala dala = petal/leaf; decoded vocabulary uses this
tal + ala "palm-tuber" = taro Jayaweera: "tal-ala" = Colocasia; SESSION_NOTES correction
tadala (unitary) Plant name Ceylon plant list; originally identified as Borassus

Key finding: Sanskrit dala-sAriRI = Colocasia antiquorum (literally "leaf-bodied" = taro). This supports the taro identification — taro is literally "the leaf plant" in Sanskrit.

Palmyra palm in Sinhala = tal (< Sanskrit tAla), NOT tadala. The paper (main.tex line 611) still has uncorrected Borassus identification.

22. BRITISH MUSEUM CATALOG (WICKREMASINGHE 1900) — KEY FINDINGS

23. BODLEIAN MANUSCRIPTS — YOGAMUKTAVALI-SAMGRAHA (CRITICAL PARALLEL)

Source: Liyanaratne, "Sri Lankan Medical Manuscripts in the Bodleian Library," JEAS Vol. 2 (1992). Full text already at: references/sinhala_medical/bodleian_sri_lankan_manuscripts.txt

MS Sansk.c.123(R) — Yogamuktavali-samgraha ("Pearl-string of Medical Compositions")

  • Author: Don Hendrik Samaratunga of Alutgama (Kalutara District)
  • Date: 1855 AD
  • Sanskrit text with Sinhala translation (sanne)
  • 15 chapters organized by PHARMACEUTICAL DOSAGE FORM:
Ch. Sanskrit Name Preparation Type Voynich Decoded Parallel
1-2 peya kanda Gruels (4 types) —
3 modaka kanda Confections —
4 leha kanda Electuaries ea? (cow-product)
5 curna kanda Powders ugeda (476 tokens)
6 kalka kanda Pastes —
7 gutika kanda Pills gula (111 tokens)
8 taila kanda Oils meda (425 tokens)
9 ghrta kanda Ghee ea (339 tokens)
10 nasya kanda Nasal applications —
11 anjana kanda Eye applications —
12 kvatha kanda Decoctions uteda (323 tokens)
13 sveda kanda Sudation seda (attested)
14 dhupa kanda Fumigations —
15 pralepa kanda Plasters —

This is the strongest structural parallel yet. The Yogamuktavali-samgraha organizes ALL pharmaceutical knowledge by preparation type — matching the decoded Voynich "state-marker" paradigm exactly. 7 of 15 chapter categories have direct decoded parallels.

MS Sansk.c.125(R) — Vaidyalankara-samgraha ("Ornament of the Physicians")

Contents include: drug collection rules, weights/measures, 7 types of kasaya (decoction), oil preparation proportions (kalka:sneha:liquid ratios), oil boiling degrees (mrdupaka etc.), specific oils by type (sesame=talatelehi, coconut=poltelehi, castor=endarutel, mustard=abatel), drug groups: mahapasmul, sulupasmul, trijataka, caturjataka, pancakola. Published edition: ed. Robert Batuvantudawe, Colombo 1950.

MS Sinh.d.5(R) — Tailavidhiya (Oil Preparation Manual)

50+ named oil preparations with ingredients and instructions. Organized by drug groups (gana).

MS Sinh.d.3(R) — Medical Compendium

25. SINHALA CORPUS COMPARISON (Tipitaka, 55M chars)

Downloaded the full Buddha Jayanthi Tripitaka Sinhala translation (207,293 text blocks, 55 million characters) and compared word usage patterns against decoded Voynich.

Function word frequencies in real Sinhala:

  • ගෙණ (gena, "having taken"): 49,459 occurrences
  • කොට (koṭa, "having done"): 57,296 occurrences ← CLASSICAL form
  • කර (kara, "having done"): 7,485 occurrences ← MODERN form
  • ද (da, question/also): 186,382 occurrences
  • ම (ma, self/emphasis): 41,577 occurrences
  • බෙහෙත (behet, "medicine"): 1,213 occurrences (even in Buddhist text!)
  • මේද (meda, "fat"): 1,217 occurrences (in "32 parts of body" recitation)
  • ලෙඩ (leda, "illness"): 248 occurrences
  • උගුර (ugura, "throat"): 81 occurrences

Pattern matches:

  1. Participial chaining confirmed: koṭa gena = 558× in corpus. Same structure as decoded Voynich "gena gala" (take then strain), "gena tha" (take then place).
  2. Object-Verb order confirmed: "siwura gena" (robe take) = same as "ula gena" (water take).
  3. Da clause-boundary confirmed: 186,382× in corpus, always clause-final.

The koṭa problem:

Classical Sinhala uses koṭa (57,296×) as dominant past participial. Decoded Voynich has ZERO koṭa. RESOLVED: H12 decoder CANNOT produce koṭa — no /o/ vowel (EVA o → /u/), no retroflex /ṭ/. The decoder uses -la suffix instead (6,199 tokens), which IS the modern Sinhala conjunctive participle (karala, genala, ugala). This is a limitation of the 4-vowel encoding, not evidence against the hypothesis.

26. VOWEL COLLAPSE ANALYSIS (4-vowel → 12-vowel mapping)

H12 decoder has 4 vowels (a, e, i, u). Real Sinhala has 12+ (a, ā, æ, ǣ, i, ī, u, ū, e, ē, o, ō).

Overall compression: 1.14:1

  • 1,470,278 dictionary words → 1,284,970 collapsed forms
  • 1,148,341 forms (89.3%) have NO collision at all
  • Most collisions are vowel-length variants (ula vs ulā vs ūla) = same root

The o→u collapse is the ONLY source of real semantic ambiguity:

Decoded Could also be Different meaning?
ula (spring) ola (pot/lamp) YES — distinct
ura (chest) ora (edge/bank) YES — distinct
gula (pill) gola (ball) YES — distinct
kura (chick) kora (lame) YES — distinct
uda (above) oda (creek) YES — distinct
uta (upward) ota (that) YES — distinct

NOT affected by o→u (these have no o-form collision):

ala, gala, kara, mara, gara, ara, meda, ena, gena, seda, leda

Key finding:

Only 1.2% of vocabulary is affected by o→u ambiguity. The 4-vowel system creates manageable, identifiable ambiguity — not chaos. The koṭa→kuta collapse is a specific instance of this pattern. Context-dependent disambiguation is feasible.

Implications for the paper:

  • The narrow vocabulary is NOT caused by vowel collapse (only 14% compression)
  • The o→u collapse creates specific identifiable ambiguities (ula/ola, ura/ora, gula/gola)
  • A future refinement could attempt to recover the /o/ vowel from context

27. VOCABULARY CONCENTRATION — REPETITION IS NORMAL

Compared decoded Voynich vocabulary concentration against real Sinhala texts and published research on medieval recipe text vocabulary.

Comparison table:

Metric Decoded Voynich Tipitaka (Buddhist) Jayaweera (plants)
Tokens 37,024 79,614 271,330
Vocab 5,921 9,372 25,580
TTR 0.160 0.118 0.094
Top 20 cover 26.0% 21.3% 22.4%
Top 50 cover 42.0% 32.2% 31.9%
Top 100 cover 53.1% 40.9% 40.8%
Hapax 67.9% 46.9% 62.1%

Key findings:

  1. TTR: Voynich (0.160) is LESS repetitive per-token than both comparison texts
  2. Top 20: 26% coverage is normal — comparable to all text types
  3. Top 50-100: Higher than non-recipe texts but EXPECTED for pharmaceutical sublanguage
  4. Published research confirms recipe texts are "sublanguages" with lexical closure
  5. Medieval recipes across all cultures follow rigid INGREDIENT + QUANTITY templates
  6. The word "kalandayi" (weight unit) appears 8× in a single real Sinhala recipe passage

Real Sinhala recipe comparison (Bodleian MS Sinh.a.2(R)):

kottamalli dekalandayi, valmi dekalandayi, handun kalandayi,
papiliya kalandayi, miris kalandayi, ...
kalanduru ala tun kalandayi, komarika ala dekalandayi,
vatura ata ekata kakara hat velak denu

Structure: ingredient + measure, ingredient + measure, water + amount, boil, give. "kalandayi" repeats 8×; "ala" (tuber) appears twice; "vatura" (water) for liquid. IDENTICAL structure to decoded Voynich: ula gena (water take), ugeda (drug) repeated, gala (strain), tha (place).

Consecutive word repetition:

  • Voynich: 2.9% consecutive duplicates (in 700-word sample)
  • Tipitaka: 0.1% consecutive duplicates
  • Higher in Voynich but explained by recipe format (same category term per ingredient)

VERDICT: The "repetition problem" is a genre feature, not a decoder artifact.

28. GRAMMAR PATTERN COMPARISON — SINHALA vs DECODED VOYNICH

Downloaded and analyzed the Buddha Jayanthi Tipitaka Sinhala translation (55M characters, 789,614 words in 5M-char sample) as comparison corpus.

Pattern matches (grammar structure is correct):

  1. Participial chaining — Real Sinhala: koṭa gena (558×), gena gos (30×). Voynich: gena gala (13×), gena tha (14×). SAME syntactic structure.
  2. Object-Verb order — Both use SOV: "siwura gena" (robe take) vs "ula gena" (water take).
  3. -la conjunctive participle — Real Sinhala: -ල 3,765 instances. Voynich: 6,241 tokens (16.9%). This IS a real Sinhala morphological pattern, though Voynich has higher frequency.
  4. da clause-boundary marker — Real Sinhala: 186,382×. Voynich: 156 tokens. Same position.
  5. Sentence-final verbs — Sinhala: veyi (5,526×), da, nam, yi. Voynich: verb-final tendency.
  6. Reduplication — Sinhala: 183 consecutive doubles in 789K words (0.02%). Voynich: higher rate, but Sinhala DOES use reduplication for emphasis/iteration.
  7. -ena suffix — Sinhala instrumental/participial. Voynich: 8.8% of tokens.
  8. gena family — Largest verb family in both Sinhala (49,459×) and Voynich (810+ tokens).

Major anomaly — THE U-PREFIX PROBLEM:

Source u-initial words % of all words
Real Sinhala (Tipitaka) 10,255 1.3%
Sinhala with o→u collapse 14,186 1.8%
Decoded Voynich 15,026 40.6%

31x overrepresentation of u-initial words in decoded Voynich.

Root cause: EVA word-initial 'o' (22.2% of words) and 'qo' (14.6% of words) both decode to u-. Rule 21 treats 'q' as silent (it always precedes 'o'). So ~37% of all EVA words decode to u-initial. This is a well-known statistical feature of the Voynich manuscript (o/qo word-initial dominance).

In real Sinhala, u-initial words are mostly Buddhist terminology (upan=born, upada=arising). They are NOT a productive morphological prefix.

The decoded Voynich uses u- as if it's a determiner or article ("THE-crude-drug", "THE-decoction", "THE-pill") — but Sinhala has NO article system.

This is the single largest structural mismatch between decoded Voynich and real Sinhala.

Possible interpretations:

  1. The initial EVA 'o'/'qo' is NOT a vowel u- — it may be a scribal convention, word-boundary marker, or represent a different phonological element
  2. H12 Rule 21 (q→silent) is wrong — 'q' may encode a consonant
  3. The source language uses u- as a productive prefix (not standard Sinhala)
  4. The u- prefix might represent a Pali/Sanskrit prefix (ud-/ut- = upward/out) that was productive in pharmaceutical terminology but not in general prose

Other grammar patterns in decoded Voynich:

  • -eda suffix (7.0%): ugeda (470), meda (444), uteda (320), leda (127) = the "state-marker" pattern. Not a standard Sinhala suffix.
  • -ara suffix (6.4%): gara (327), ugara (300), utara (229)
  • State-marker compounds u+ROOT: 12.3% of all tokens
  • Single-syllable function words: ula, ura, eda, ena, ara, uga, uta, ea, ala, ga account for substantial token share

Word-initial frequencies compared:

Initial EVA (%) Decoded (%) Sinhala (%) Match?
u-/o- 22.2+14.6 40.6 1.3+0.5 31x overrep
a- 5.0 ~5.0 4.7 YES
e- 0.4 ~3.5 2.4 Close
k- 3.2 ~3.0 7.7 Under
s- 11.8 ~3.5 8.1 Under
m- 0.0 ~2.5 9.2 Under
g- 0.0 ~3.0 1.6 Close

Note: EVA initial 'ch' (16.1%) decodes to various forms; 'd' (9.7%) and 's' (11.8%) also have high EVA frequencies but their decoded distributions need checking.

29. ud-/ut- PREFIX IN PHARMACEUTICAL SANSKRIT

Investigation into whether the 40.6% u-initial anomaly in decoded Voynich is explained by pharmaceutical Sanskrit/Pali ud-/ut- prefix concentration.

Findings: ud-/ut- IS disproportionately concentrated in medical texts:

  • udaka (water) = standard pharmaceutical vehicle
  • udvartana (upward massage), utkarika (poultice), utklesha (emesis)
  • Panchakarma preparatory procedures heavily saturated with ud-/ut- terms
  • Maps to extraction, emesis, massage, anatomical terms

But: Even in the Bhesajjamanjusa, u-initial words are only ~1.8%. The 40.6% in decoded Voynich remains a 22x overrepresentation vs the most u-heavy text we can find. Partly explained by EVA 'o' and 'qo' dominance (Rule 21 treats 'q' as silent), but the gap is still the largest structural anomaly.

30. FOLIO STRUCTURE ANALYSIS (f49v, f66r, f76r, f103+)

f49v — "Alphabet Page" / Syllabary Key

  • 25+ individual Voynich characters listed vertically in left margin
  • First 5 have Arabic numerals 1-5 written next to them
  • Under H12, each character decodes to an individual Sinhala phoneme:
    • Consonants: f(ca), r(ra), k(ka), s(sa), p(pa), d(ga)
    • Vowels: o(u), y(a), e(e)
  • Several positions illegible (* in transcription) — possibly less common chars (sh=ma, ch=devoicer)
  • CONSISTENT WITH a writing system key/reference page
  • Scholars note this may have been added after main text, or may be an early decipherment attempt

f66r — Labels + Second Alphabet Listing

  • L section: 15 single words (labels around illustration)
    • Decoded: rara, ralasa, ura, gara, agacula, sala, salaca, cara, utesa, agala...
  • M section: 30 individual characters — another alphabet listing similar to f49v
  • Has reclining figure at bottom with "der Mussteil" in German (Latin script)
  • One of very few folios with readable text in a known language

f76r — Bathing Section Labels

  • 9 single characters labeling parts of bathing illustration
  • Decoded: sa, ga, (silent), sa, u, la, ka, ra, sa
  • Likely abbreviations for ingredients or anatomical points

f103+ — Recipe Section: Problem-Then-Solution Structure

  • ~977 short paragraphs across 21 folios
  • Each marked with marginal star (varying types)
  • Stars vary: tailed vs untailed, red center vs yellow vs blank
  • f103/f116 (outer bifolio) specifically lack tailed stars

KEY FINDING: p/f-initial recipe header pattern

  • 161/977 paragraphs (16.5%) start with p/f-initial word (pa-/ca-)
  • These appear roughly every 6 paragraphs (average gap 6.1)
  • Pattern on f103r: P.1(pedala), P.5(puarala), P.13(pudara), P.18(puleda), P.21(pea), P.30(pulagada), P.37(peda), P.48(pularara), P.52(pedala)
  • Between headers: d/s/o/y-initial words (ingredients, instructions)
  • CONSISTENT WITH Ayurvedic recipe structure:
    1. Header paragraph (condition name + formula name) — p-initial
    2. 4-6 paragraphs of ingredients, preparation, dosage
  • Different star types likely mark these categories: problem then solution
  • ~193 dark-painted stars ≈ 204 illustrated pages elsewhere (possible indexing)

Three folios with single-character listings:

  1. f49v: 16+ readable characters (plus illegibles)
  2. f66r: 30 characters in M section
  3. f76r: 9 characters as illustration labels

32. f79r SPECIFIC LINE ANALYSIS (User-Identified Patterns)

User noticed structural patterns on f79r (recipe/bathing section).

Lines 7, 12, 25, 39 — first words:

Line EVA Decoded Meaning Pattern
P.7 polchedy puleda bloomed + then p-initial (recipe header)
P.12 qokchy uga learned/fig-tree instruction paragraph
P.25 cholchey ulea (compound) instruction paragraph
P.39 polkeey pulagēa (compound) p-initial (recipe header)

Lines 7 and 39 are RECIPE HEADERS (p-initial), 12 and 25 are INSTRUCTIONS. User correctly identified that these lines "look different" — they start new recipes.

Lines 20, 34 — first TWO words:

Line Word 1 Word 2 Significance
P.20 a (vowel) mala (flower/garland/stool) Plant/symptom reference
P.34 leula keda (crude/base form DRY) Pharmaceutical preparation term

P.34 starts with keda as second word — names a preparation TYPE (crude decoction). This suggests sub-structure within recipes: not just header + ingredients, but also preparation-type labels.

Full p-initial pattern on f79r:

Headers at: P.7, P.13, P.21, P.26, P.31, P.35, P.38, P.39 = 8 recipe headers in 44 paragraphs = ~5.5 paragraphs per recipe

33. f66r UNKNOWN CHARACTERS

On f66r's M section (individual character listings), two entries are transcribed as 'x' by ALL transcribers (H, C, F, U) — meaning these glyphs don't match ANY known EVA character:

  • M.10: EVA 'x' — unidentified glyph
  • M.24: EVA 'x' — unidentified glyph
  • M.22: EVA 'c' (bare) — extremely rare, only appears alone in this context

User observed that "the character after the word doesn't look like a character I have seen before."

Possible interpretations:

  1. Numerals from a different system (Arabic, Sinhala, Brahmi)
  2. Sinhala/Brahmic characters written directly (not encoded in Voynichese)
  3. Abbreviation marks or punctuation
  4. Characters from a script the encoder borrowed but didn't fully integrate
  5. Later additions by a different hand (like the German "der Mussteil")

If these are NUMERALS — they could provide a Rosetta Stone for number identification. If they are Brahmic characters — they would directly confirm the script family.

34. TESTABLE PREDICTIONS (New)

Test 1: Star-Type Correlation (BLIND TEST)

If someone independently digitizes which paragraphs have tailed vs untailed stars, red vs yellow centers, we can test whether star type correlates with p-initial (header) vs non-p-initial (instruction). Star data and decoding are completely independent. Expected: Different star types mark different content categories.

Test 2: Recipe Internal Coherence

Check if vocabulary WITHIN a recipe (between two p-initial headers) is more self-consistent than vocabulary ACROSS recipe boundaries. Use cosine similarity or Jaccard overlap. Expected: Higher within-recipe than between-recipe similarity.

Test 3: f49v Character Order

Compare the listed character sequence on f49v against traditional Sinhala/Brahmic syllabary orderings (akshara pata). Even partial match is significant. Expected: Some correspondence to traditional ordering.

Test 4: f66r Unknown Character Identification

Cross-reference the 'x' glyphs against Sinhala numeral forms, Brahmi script elements, or other Indic character inventories. Expected: If identifiable as Brahmic, strong evidence for the script hypothesis.

Test 5: Recipe Header Semantic Consistency

Check if p-initial header words consistently relate to medical conditions/dosage forms across the entire recipe section (not just f103r). pedala(suffering), pea(drinking/beverage), pula(opened/bloomed=pustule?) etc. Expected: Header words should cluster around condition names and dosage forms.

35. HONEST ASSESSMENT — WHERE WE STAND

Evidence that IS mounting:

  1. Cross-tradition attestation: 10/13 decoded terms found in 13th c. Bhesajjamanjusa
  2. keda/kleda breakthrough: l-deletion documented in Pali grammar (not our invention)
  3. Yogamuktavali parallel: 7/15 pharmaceutical chapters match decoded state-markers
  4. Plant names: 12/16 confirmed in Jayaweera's Ceylon medicinal plants
  5. Grammar: Participial chaining, SOV order, -la suffix, da marker all correct
  6. Vocabulary: TTR normal for recipe sublanguage; repetition is genre feature
  7. Folio structure: f103+ problem-then-solution pattern with semantic content matching visual formatting
  8. Real Sinhala recipe (Bodleian MS): identical ingredient+measure template structure

The gap that remains:

The main vulnerability is the gap between "real Sinhala words" and "readable Sinhala text." Individual words match dictionaries, but we haven't produced a complete, independently verifiable connected passage that an unbiased Sinhala scholar would read as natural prose.

The largest anomaly:

u-prefix overrepresentation (40.6% vs 1.3%) = 31x. Even pharmaceutical Sanskrit only reaches 1.8% u-initial. This either means:

  • EVA initial o/qo encodes something other than u- (scribal convention? word-boundary?)
  • Rule 21 (q→silent) needs revision
  • The source language uses u- differently than standard Sinhala

What would strengthen the case most:

  1. A complete readable recipe passage verified by a Sinhala scholar
  2. Physical access to Nava Jatiya Niganduwa (600yr old pharmaceutical glossary)
  3. Identification of the f66r unknown characters as Brahmic
  4. Resolution of the u-prefix anomaly

What was NOT useful (time saved for future):

  • Manchester MSS: All Buddhist, no medical content
  • Chandrasena: Uses English for prep terms, limited Sinhala vocabulary
  • CCRAS portal: Down/unavailable
  • About 30% of investigation time produced 90% of value

37. TEST RESULTS: RECIPE COHERENCE (Passed)

Method:

Measured Jaccard similarity of word sets between consecutive paragraphs. Compared within-recipe similarity vs across-boundary vs random baseline.

Results:

Comparison Mean Jaccard N pairs
Within-recipe (consecutive paras) 0.0459 814
Across-recipe boundary 0.0275 159
Random paragraph pairs 0.0288 1,000
Adjacent recipe word-sets 0.0998 159
  • Within-recipe = 1.67x higher than across-boundary
  • Permutation p-value: p < 0.0001 (0/10,000 permutations ≥ observed)
  • Same-folio r/v similarity: 0.2173 (n=9)
  • Different-folio similarity: 0.1964 (n=201)

Interpretation:

The p-initial headers mark real content boundaries. Vocabulary genuinely changes at recipe boundaries — different recipes use different ingredient/instruction sets. This is strong evidence that the decoded text has internally coherent semantic structure.

38. TEST RESULTS: f49v CHARACTER ORDER (Partial Match)

Method:

Compared f49v character sequence against standard Brahmic akshara ordering.

Results:

  1. Consonant order does NOT match Brahmic akshara order (18/36 inversions)

    • f49v: ca, ra, ka, sa, pa, ga
    • Brahmic: ka, ca, ṭa, ta, pa, ya, ra, sa

  2. BUT vowel triplet (u, a, e) repeats perfectly 3 times: u a e | u a e | u a e | a a Pattern length 3: matches 3/3 complete cycles

  3. Illegible glyph &140 repeats at regular intervals (positions 6, 14, 21) = same unknown character, possibly sh(=ma) or another multi-stroke glyph

  4. Core H12 inventory is represented:

    • 6 consonants: ca, ra, ka, sa, pa, ga (+ possibly ma if &140=sh)
    • 3 vowels: u, a, e
    • Missing: ta, da, na, la (less frequent); i (rarest vowel)
    • Multi-character mappings (sh, ch, ct, ck, cp) don't need entries

Interpretation:

f49v is NOT a traditional Sinhala syllabary chart (wrong order). BUT the repeating vowel triplet structure IS consistent with an abugida demonstration — showing consonant+vowel combinations. This is how you'd teach/document the encoding system: "this character makes sound X, combine with these vowels."

The page documents the CORE characters of the writing system (the ones that appear as single glyphs), not the full phoneme inventory (which includes digraphs/combinations).

39. TEST RESULTS: RECIPE HEADER SEMANTIC CONSISTENCY (Passed)

Method:

Analyzed all 161 p/f-initial header paragraphs across the full recipe section. Compared first-word semantics, root distribution, and category enrichment vs 814 non-header paragraphs.

Key Results:

1. Header first-words cluster around 3 roots:

Root Count % Medical meaning
pu- (pula, puleda...) 78 48.4% opened/bloomed/swollen; puṭapāka (crucible method)
pe- (peda, pedala, pea...) 33 20.5% suffering/affliction (< Skt pīḍā); drinkable (< Skt peya)
pa- (padara, pala...) 33 20.5% fruit; step/method
ca-/cu- (f-initial) 10 6.2% small (cula); powder (curna)

2. Non-headers have completely different initial distribution: u- (23%), a- (21%), g- (19%), s- (14%), t- (12%) — zero p/f dominance

3. Semantic category enrichment:

Category Headers Non-headers Enrichment
Dosage form words 7.2% 3.3% 2.2x in headers
Pharmaceutical actions 4.1% 11.4% 2.8x in non-headers

Headers contain condition names and preparation labels. Non-headers contain instructions (gena=take, gala=strain, kara=make, tha=place). This is exactly the expected semantic differentiation.

4. Second-word comparison:

  • Header 2nd words: ara(5), utara(4), mēda(4), meda(4) — preparation terms
  • Non-header 2nd words: ea(36), ugēa(28), mea(27), ena(27) — ingredients/process

5. Key medical terms confirmed:

  • pedala/peda (7x) = suffering/affliction (< Skt pīḍā) — condition name
  • pea (3x) = drinking/beverage (< Skt peya) — dosage form name
  • pula (9x) = opened/expanded/swollen — condition or prep term
  • curna (via cu-) = powder — dosage form name

Interpretation:

The p/f-initial headers are semantically differentiated from non-headers. Headers name CONDITIONS and PREPARATION TYPES. Non-headers provide INSTRUCTIONS and INGREDIENTS. This is consistent with real Ayurvedic recipe structure: "For [condition], [dosage form]: take X, grind Y, strain Z, place in W."

36. CORRECTIONS NOT YET APPLIED TO PAPER
