P09 · Sītā Enters the Stage

Feminine ā-Stem, Directional-Sticker Prefixes

Draft · in review

Teacher notes / sources (students may skip)

Corresponds to: Perry Lesson IX (§162–167) ＝ SKT บทที่ 9. Two tracks: the feminine ā-stem (senā type) and verbal prefixes (upasarga)——the latter being the richest mine for elevated Thai vocabulary (U15 anchor redeemed early). Sītā enters the main storyline from this lesson (นางสีดา in the Ramakien, the character students are most emotionally invested in).

① AnchorA cognate hiding in Thai — recognise it first, then learn its form0. Anchor (5 minutes)

"Today's new character is someone you've known since childhood: นางสีดา (Thai: "Lady Sītā")——Sītā (สีดา ← sītā).
Her word-family is yours too: กัญญา (Thai: "maiden") ← kanyā; ฉายา (Thai: "shadow; by extension, a monk's honorary name") ← chāyā (in Sanskrit the original meaning is only shadow/shade);
ภรรยา (Thai: "wife") ← bhāryā; and from L0, วิทยา (Thai: "knowledge") ← vidyā and ภาษา (Thai: "language") ← bhāṣā——
all feminine words ending in -ā; today we see how they 'wear their hats.'
One prefix word to open with: อวตาร (Thai: "avatar, divine descent") ← avatāra, 'to descend into the world'——root tṛ (to cross/pass) plus the directional sticker ava (downward):
avatarati (he descends——in a religious context, 'to take avatāra/manifest on earth'). The word avatar you use every day is its noun form, avatāra."

② StoryA micro-story you can follow, with only one new form1. Story (CI Micro-narrative——Sītā Enters)

๑

सीता ग्रामम् आगच्छति।

sītā grāmam āgacchati.

Sītā comes to the village.

๒

कुमारः सीताम् पश्यति।

kumāraḥ sītām paśyati.

The boy sees Sītā.

๓

सीता भाषते।

sītā bhāṣate.

Sītā begins to speak.

๔

सीता पृच्छति किम् अवगच्छसि।

sītā pṛcchati — kim avagacchasi?

Sītā asks——do you understand?

๕

अवगच्छामि

avagacchāmi!

I understand!

(๔–๕: avagacchati (to understand) ＝ ava (downward) ＋ gacchati——"to sink down ＝ to understand." From this lesson it becomes a classroom phrase: กิม อวคจฉสิ?)

③ Sentence-buildingBuild it sentence by sentence from words you already have2. Sentence-Building (MT Track)

"Feminine -ā words take their hats most economically: subject hat ＝ base form (sītā, kanyā——nothing added),
object hat ＝ -ām (sītām, kathām——you already used kathām in P07)."
"Prefixes are directional stickers: they attach before the verb, and the verb itself does not change:
ā- (toward here) ＋ gacchati ＝ āgacchati to come——known since P05;
ava- (downward) ＋ gacchati ＝ avagacchati to understand; ava- ＋ tarati ＝ avatarati to descend/take avatāra.
Change the directional sticker, and the root needs no relearning."

Sentence-building chain: gacchati → āgacchati (recycled) → avagacchati → kim avagacchasi? → sītā grāmam āgacchati

Listen4. Listening (Audio List)

▶ audioAudio checklist for this lesson — placeholders in the preview; the live version uses pre-baked Matcha audio + real recordings (played when logged in, not hot-linked).

Five story sentences in two versions; clips: gacchati→āgacchati→avagacchati in sequence (hearing the sticker); hat pairs sītā/sītām, kanyā/kanyām; kumāraḥ sītāṃ (aḥ＋s held).

Use5. Use (Exercises)

Sticker drill: teacher calls a direction (in Thai), students attach the prefix and form the word (recast).

Hat quick-fire: sītā/kanyā/kathā/vidyā × subject hat/object hat (ten items, oral).

Activate classroom phrase: from this lesson the teacher asks kim avagacchasi?——students reply avagacchāmi／na avagacchāmi (genuine communication).

Decoder Card recycling: อวตาร (Thai: "avatar") broken down live as ava＋tāra; ประกาศ (Thai: "to announce") ← pra-kāśa; วิเคราะห์ (Thai: "to analyze") ← vi-graha (vi- 'to see apart/dissect'——memorize the shape now, formal introduction in W11; prefix decoding from Thai newspaper headlines, first taste of the U15 treasure-trove).
