L00 · Unveiling Lesson

The first sentence of the course is Sanskrit: namo namaḥ!(นโม นมะ — palms together)— from today onward this is the course's fixed greeting(ritual building block, not analyzed). Then ask directly.

Unveiling ① "Half the Dictionary"

"Let's try an experiment. Who can name a 'high-register' Thai word — the kind you hear in royal news, at temples, in court?"
(Students offer whatever comes to mind: ราชดำเนิน, บริจาค, อนุญาต … Teacher writes them on the board without explanation.)
"In a moment you'll crack these words yourselves. First, one fact: Thongprasert (1977) surveyed the Royal Institute Dictionary
and found that more than half the entries derive from Pali–Sanskrit※. Your 'high Thai' was always a world of Sanskrit."

※ Pedagogical red line: say only "more than half" as a qualitative statement, with the source cited (Royal Institute Journal 3(2):37–40, as cited; original publication pending verification); it is forbidden to say 95%, or to give any precise percentage broken down by register.

Unveiling ② "Who Designed the Alphabet?"

"Open the table of contents of any Thai dictionary. ก ข ค ฆ ง — who fixed this order?
Not the Thais. This is the five-class phonetic matrix that Indian phoneticians designed for Sanskrit more than two thousand years ago (the Pāṇinian tradition, systematized by the 4th century BCE); this alphabet only spread to Southeast Asia with Indian scripts around the 5th–6th century CE:
Velar ก ข ค ฆ ง ＝ क ख ग घ ङ / Palatal จ ฉ ช ฌ ญ ＝ च छ ज झ ञ /
Retroflex ฏ ฐ ฑ ฒ ณ ＝ ट ठ ड ढ ण / Dental ต ถ ท ธ น ＝ त थ द ध न /
Labial ป ผ พ ภ ม ＝ प फ ब भ म. In exact correspondence.
Of your 44 consonants, 34 map directly to Sanskrit letters — Thai script contains characters prepared for Sanskrit,
more than modern Thai itself uses. You have been using Sanskrit's writing system for 700 years."

(Write the five-row comparison matrix on the board; have students read the Thai row aloud while the teacher reads the Devanagari row — "Hear that? The same set of sounds.")

Unveiling ③ "The Five-Rung Ladder of กิน (Thai: 'to eat')"

"For the single act of 'eating,' how many words does Thai have?" (Write as a ladder on the board, climbing from bottom to top:)

"See the pattern? Every rung higher, Sanskrit and Pali do more of the work.
Learning Sanskrit is not learning a foreign language — it is receiving the key to the uppermost register of your own."

Distribute the card (260611-DecoderCard-v1-內容稿 printed edition). "This card has 30 rules on the front. This semester we look at them only when needed. Today we use only the 4 starred ones."

★ 4 rules (taught through words, not abstract explanation): A1 ś/ṣ/s→ศ/ษ/ส; B1 ṛ→ริ/รึ/ฤ; B2 consonant clusters insert a; D1 final -a drops.

Claiming words one by one (Teacher writes Thai on board → Students use card to reverse-engineer → Teacher adds Devanagari):

Close: "Ten words — and not one was 'memorized.' This course will work exactly this way through to the end: decode, don't rote-learn."

Introduction Ritual (Building Block): Each student says one sentence — mama nāma ___(my name is——)— around the class. nāma is Thai นาม (Thai: "name") (นามสกุล "surname," นามบัตร "name card")— you use it every day.(The grammatical formal home of mama／nāma comes later; today it is only ritual. From now on every session opens with namo namaḥ and new students introduce themselves with mama nāma — the classroom language is Sanskrit from day one.)

First Four Segments of Bangkok's Name(a promise to read the full text by semester's end):

กรุงเทพมหานคร อมรรัตนโกสินทร์ มหินทรายุธยา มหาดิลกภพ …
- กรุงเทพมหานคร ＝ mahā-nagara(the two words just claimed!)
- อมรรัตนโกสินทร์ ＝ amara "immortal" ＋ ratna "jewel" ＋ โกสินทร์ (an epithet of Indra) — together "the immortal jewel of Indra"
- มหินทรายุธยา ＝ mahā+indra ＋ ayudhyā(← Ayodhyā, city of Rāma)
"The world's longest capital name is a Sanskrit hymn. By semester's end, you will read all 168 characters."

Course Contract(state the rules openly, reduce fear):

1. No final exam asking students to "translate a Sanskrit passage." Grade ＝ decoding 25% ＋ controlled-range grammar test 25% ＋ authentic-text contact 25% ＋ personal project "My Sanskrit Fragment" 25%.
2. Everyone has a kośa (personal word-store)— those ten words are the first batch, and you already knew them. A spaced-repetition system will prompt you to review.
3. Grammar tables are not memorized first. Use them in sentences until fluent; then in the "Crystallization Lesson" the tables get their names — tables are a reward, not a gate.
4. Transliteration note (one line): the course materials follow the printed edition's āi/āu spelling, which equals standard IAST ai/au.

Pair Decoding Race(use card; teacher announces only the Thai): บิดา, บุตร, เนตร, เมฆ, ดารา, วายุ, สตรี, กวี, ศิษย์, อาจารย์(answers on Decoder reverse, numbers 29/31/79/65/63/68/38/55/44/43).

Field Assignment ①(share at Session 1 next week):

"Take three photographs: your hometown, this university, a temple you visit often — and find one sign or place-name containing Sanskrit at each location.
Use the card to reverse-engineer the Sanskrit original. If you can't get there, bring it next week and we'll decode it together."

Preview P1:

"This time next week you will produce your first Sanskrit sentence — and not recite it from memory, but construct it yourself."
