P16 · The New Tone of "Should/Might" + Claiming Your Family's Cow
Draft · in reviewTeacher notes / sources (students may skip)
Corresponds to: Perry Lesson XVI (§206–209) = SKT บทที่ 16 (สัปตมีวิภักติ ปรัสไมบท นามนาม ฤ-การันต์ และโค-ศัพท์). W9 second half. Sources: Perry §206–209 (backbone: paradigm + four shades of meaning + full go table) + Goldman §14.12–14.15 (mode-sign derivation, the -uḥ pitfall stated explicitly) + Goldman §21.3 go paradigm cross-check + Ruppel Ch.12 (imperfect/potential side-by-side comparison method) — four-source mining notes in 260702-P13-P30-四源挖料. The SKT_Thai volumes 16–20 have OCR damage (misaligned ending tables, not manually proofread); this lesson does not cite any SKT original-text example sentences, using only Perry/Goldman original examples plus self-authored sentences; the term สัปตมี follows the already-verified entry in 260611-課序映射-SKT-Perry-07單元. Two core items: a new tone — not a command, but "should/might/may it be so" (one notch softer than the command voice of P14/P15); claiming the โค etymology — the Thai word for "cattle," โค, is exactly the Sanskrit go itself, though on the Sanskrit side it's a great shape-shifter (gau/gav/go, three forms). Perry §208 (continuing ṛ-stem kinship words) has already been absorbed via P15's front-loading, so this lesson does not re-teach it.
"Thai โค (cattle, formal written register; everyday speech says วัว) — is exactly Sanskrit go. On the Sanskrit side its temperament is quite strange:
'cattle (subject)' is gauḥ, 'sees the cattle' is gām, 'with the cattle' is gavā — the same cow wears several faces,
and Thai borrowed only the plainest of them (the go-stem itself)."
"We also learn a new 'tone' today. In the last two lessons you learned to command (gaccha!/labhasva!). Today, learn the softer notch:
'you should go,' 'he might go,' 'may I be able to…' The Thai term for this is สัปตมี (saptamī, literally 'the seventh' —
which shares a name with the noun's 'where' case, the seventh case; this is the verb's seventh mood — distinguish by context, don't mix them up)."
Lesson sound rule (A2, deepened, taught alongside the vocabulary): you already know โค's ค (written voiced, read voiceless, P01). Today the whole stop-consonant correspondence table is laid out: Sanskrit stops go straight across "by row" into Thai — the voiceless row k c ṭ t p→ก จ ฏ ต ป, the aspirated row kh ch ṭh th ph→ข ฉ ฐ ถ ผ, the voiced row (written voiced, read voiceless) g j ḍ d b→ค ช ฑ ท พ. โคตร (← gotra, cattle-pen → clan; also the source of the colloquial intensifier "super-") straddles two rows in one word: g→ค (voiced row) + t→ต (voiceless row, straight across).
(Every verb recycled: vad←P01, paś←P05, gam←P01; vas (dwell) is a self-authored lightweight item, appearing only in ๓ for ear-training, not entered into the store. Nouns: go newly entered into the store; nadī←P11, muni←P13's reference word makes its debut appearance (มุนิ), bāla←P03, pitā←P15. The only new grammar item is one thing: swapping in the "should" tone tail. The sandhi is all old rules: ๑ bālaḥ→bālo (ḥ+voiced→o, recycled from P11 hyo); ๓ gauḥ nadīm→gaur nadīṃ (ḥ+voiced→r, recycled from P02), muniḥ ca→muniś ca (ḥ+c→ś, recycled from P02). Recognition points per sentence: ๑๒ โค; ๓ โค/นที/มุนิ; ๔ นที/โค.)
Thread one: the wish-switch e.
"Last lesson's command 'you' was lopping the tail (gaccha!); the 'should' tone's 'you' is -eḥ: paśyeḥ (you will see), vadeḥ (you should say).
There's only one secret: the stem-final a fuses with a tiny ī into e — so this whole tone rings with '-e-' throughout.
'He should/might' = -et: gacchet. 'May I…' = -eyam (with a little y padded in the middle): paśyeyam."
▸ Load-reduction point (Goldman §14.14–15): for a-class verbs (everything you've already learned), the mode-sign is always heard as "stem+e" — the only thing to memorize is the small tail-table below; e never touches a vowel-initial tail directly, a य् is padded in between (-eyam/-eyuḥ).
Thread one continued: the full table (bhū substituted in; Perry §206's vad- paradigm is structurally identical)
| Singular | Dual | Plural | |
|---|---|---|---|
| he | भवेत् bhavet | भवेताम् bhavetām | भवेयुः bhaveyuḥ |
| you | भवेः bhaveḥ | भवेतम् bhavetam | भवेत bhaveta |
| I | भवेयम् bhaveyam | भवेव bhaveva | भवेम bhavema |
"One pitfall: 'they' is NOT your usual -an (the apaṭhan style), here it's always -eyuḥ (bhaveyuḥ) —
this is the loudest ear-marker of the 'should' tone."
Thread two: go — one cow, many faces.
"go shape-shifts even more than P15's pitā/dātā. The core vowel itself swaps between au/o/av. Subject hat गौः (gauḥ);
direction hat गाम् (gām — not -am, but -ām!); instrumental hat गवा (gavā). Listen to the pattern rather than memorizing the grid:
the heavy-duty cells use gau-/gā- (subject hat, direction hat), everywhere else the plain face go-/gav- (go before a consonant, gav before a vowel) —
the same trick as P15's 'two faces,' except this time even the vowel itself changes."
| Singular | Dual | Plural | |
|---|---|---|---|
| Subject/Vocative | गौः gauḥ | गावौ gāvau | गावः gāvaḥ |
| Direction (Accusative) | गाम् gām | गावौ gāvau | गाः gāḥ |
| Instrumental | गवा gavā | गोभ्याम् gobhyām | गोभिः gobhiḥ |
| To whom (Dative) | गवे gave | गोभ्याम् gobhyām | गोभ्यः gobhyaḥ |
| From where (Ablative) | गोः goḥ | गोभ्याम् gobhyām | गोभ्यः gobhyaḥ |
| Whose (Genitive) | गोः goḥ | गवोः gavoḥ | गवाम् gavām |
| Where (Locative) | गवि gavi | गवोः gavoḥ | गोषु goṣu |
Building block (use-first, analyze-later — this lesson's set): yadi … tarhi … (if… then…).
yadi nadīṃ gacchema tarhi gāṃ paśyema — the "should" tone is exactly the standard form of the conditional sentence (Perry §207).
No Thai reflex, no hook created; the whole frame is used as-is first, its internal analysis saved for Crystallization Lesson.
TPRS wrap-up: "Who wished to see the cattle? How did father answer? Where might the cattle go?" — students chain-build sentences using -eyam/-eḥ/-et in three stages.
- "Wish-switch e (a+ī fused) + small tails: -et/-etām/-eyuḥ (he), -eḥ/-etam/-eta (you), -eyam/-eva/-ema (I) — 'they' is always -eyuḥ, never -an."
- "This tone has four uses: wishing/requesting/should/might — the standard form of the conditional sentence (yadi…tarhi); negation uses na, not the command voice's mā (P14)."
- "go's many faces: heavy-duty cells gau-/gā- (gauḥ/gām), plain face go-/gav- (goḥ/gave/gavā) — Thai โค borrows the plain face."
- "Sound-rule day (A2, deepened): the three-row stop-consonant correspondence table — voiceless ก จ ฏ ต ป / aspirated ข ฉ ฐ ถ ผ / voiced (written voiced, read voiceless) ค ช ฑ ท พ; โคตร straddles two rows (ค+ต)."
Full-table choral reading (bhavet/bhaveḥ/bhaveyam, three-stage rotation); tone-contrast slices: 🔇gaccha↔gacchet🔇 (🔇command↔should🔇, listening first for the tone difference); go's shape-shifting alternation: 🔇gauḥ↔gām🔇↔🔇gavā↔goḥ🔇 (five repetitions); both versions of the four-sentence story; sandhi slices: gaur nadīṃ / muniś ca (ḥ sandhi recycled, side by side).
(Teacher reference words: manyate/modate/śaṃsati/smarati (Perry XVI word-list new verbs; this lesson only ear-trains modate to pave the way for P17, not entered into the student page); gotva/ghāsa/jāmātṛ/budha/yugma/śrāddha wait for later lessons; duhitṛ (dictionary form) and its relation to P15's ธิดา←dhītā, see P15's etymology note, not re-covered here. If a student asks "how does this relate to yesterday's tense (P11/P13)?": same family of small tails, but no past switch a- is attached here — different tone, different switch, not proactively pre-taught.)
This week's session, candidate = Crystallization Lesson Five (collecting P16–17, pending finalization of the schedule calendar): the "should tone" active + Ā-clothing full table side by side given a formal home, + go/nau comparison (the great shape-shifter vs the model student of regularity), + a combined table of indicative/yesterday/command/should tails across all four (if front-loaded class time permits).
