P03 · The Slim-Family Verbs and the Mystery of ṇ

Teacher notes / sources (students may skip)

Corresponds to: Perry Lesson III (§107–110) = SKT บทที่ 3. Low-friction lesson (verbs same as P01, pure MT shape). The "pivot point" = SKT's own น→ณ (ṇatva) rule — cashing in the mārgeṇa mystery from P02, linking to Decoder E4. v2: All three verbs fully anchored to cognate hooks (อิจฉา/ปุจฉา/นิเวศ); lead character changed to kumāra; sound-change rule for this lesson: E4 (ṇatva). Week's section 4 = Crystallization Lesson One.

① AnchorA cognate hiding in Thai — recognise it first, then learn its form0. Anchor (5 minutes)
"Three verbs, three relatives of yours:
อิจฉา (Thai: "envy, jealousy") ← icchā (same form in both Pāli and Sanskrit) — verb icchati (he wants). Note: the original meaning is simply 'to want';
Thai has drifted toward the negative sense 'to be jealous' — this is your first 'false friend', cards marked △ are all of this type — the verb icchati itself remains the neutral 'to want.'
ปุจฉา (Thai: "a formal question in a sermon or dharma dialogue") ← Pāli pucchā — Sanskrit twin pṛcchā: verb pṛcchati (he asks).
(Pāli compressed pṛ into pu; Thai follows Pāli — this is your first 'Pāli–Sanskrit twin pair.')
นิเวศ (Thai: "residence, abode"; the นิเวศ in นิเวศวิทยา 'ecology') ← niveśa — root viś: verb viśati (he enters)."

Recycled: มรรค/เมฆ — these happen to be mārga/megha from Perry's vocabulary list for this very lesson; นคร continues as the setting.

② StoryA micro-story you can follow, with only one new form1. Story (CI micro-narrative)
कुमारः नगरम् विशति।
kumāraḥ nagaram viśati.
The boy enters the city.
रामः पृच्छति किम् इच्छसि
rāmaḥ pṛcchati kim icchasi?
Rāma asks — What do you want?
फलम् इच्छामि।
phalam icchāmi.
I want fruit.
कुमारः मार्गेण गच्छति।
kumāraḥ mārgeṇa gacchati.
The boy goes along the road.

(Notice sentences ๒ and ๓: the connected reading has almost no change — why? Section 3 will reveal it. Claim points per sentence: ๑ กุมาร/นคร/นิเวศ (root-family anchor); ๒ ราม/ปุจฉา/อิจฉา; ๓ ผล/อิจฉา; ๔ กุมาร/มรรค.)

③ Sentence-buildingBuild it sentence by sentence from words you already have2. Sentence-Building (MT track)
"Three new verbs, all with familiar endings: icchati (he wants) → 'I want'?" (Student: icchāmi)
"pṛcchati (he asks) → 'You ask'?" (pṛcchasi) "viśati (he enters) → 'I enter'?" (viśāmi)
"This family of verbs is the 'slim version' of the gacchati family, differing in just one way: the root doesn't get fat (no strengthening).
You don't need to worry about it at all — the endings carry over exactly."

Sentence-building chain: icchati → kim icchasi? → phalam icchāmi → kumāraḥ phalam icchati → kumāro nagaraṃ viśati. (Each step changes only one piece; all previously learned material from P01–02 is recycled throughout.)

Building blocks (use-first, analyze-later — this lesson's set): tat/etat (that/this — pointing at things) + ca (and, postpositive).

tat kim? (What is that?) — tat phalam! (original sentence from RSS Lesson 1) rāmaḥ kumāraḥ ca (Rāma and the boy).

(Formal home: tat/etat→P19; ca is an indeclinable.)

The Mystery of ṇ Solved (the pivot of this lesson = Sound-Change Day E4):

"Last week someone asked why mārgeṇa has ṇ and not n. The rule in one sentence: **when retroflex sounds like ร/ฤ/ษ precede it,
the following n curls into a retroflex ṇ. You have already seen it — the in พราหมณ์ (ร triggers it) and ลักษณ**ะ (ษ triggers it) comes from exactly this.
What Sanskrit is doing, your Thai spelling has preserved for a thousand years." (= Decoder E4; only this one sentence is given — no full condition table.)

Real sentences (text first; audio being aligned)

These sentences come from real classroom / native-speaker material and match this lesson's grammar. Get familiar with the text first; play buttons will appear once the audio is cut and aligned.

अभिरामः उपविशति।
abhirāmaḥ upaviśati
Abhirāma sits down RSS L3

All four story sentences in both versions; contrast clips: kim icchasi (m + vowel) vs kiṃ vadati (ṃ + consonant; vadati recycled from P01); mārgeṇa slow read. Native-sentence layer: see 眞人原句池-RSS-L1-6 — priority given to sentences that fit this lesson and near-envelope sentences for early insertion (audio cutting pending alignment workflow).

Vocabulary cards: iṣ (→icchati to want; อิจฉา (Thai: "envy") △), prach (→pṛcchati to ask; ปุจฉา (Thai: "formal question") twin pair), viś (→viśati to enter; นิเวศ (Thai: "residence")), bāla बाल (boy — Perry vocabulary III word; lesson story uses kumāra, this card is for reading recognition). Sandhi card: m + vowel → m unchanged (with audio example). Building-block cards: tat/etat (pointing that/this), ca (and, postpositive — rāmaḥ kumāraḥ ca). Rule card: E4 "the mystery of ṇ" (ร/ฤ/ษ + n → ṇ; examples mārgeṇa, พราหมณ์ (Thai: "brahmin") = ร triggers, ลักษณะ (Thai: "characteristic") = ษ triggers).
