๑What tone does ต give?class isn’t trivia — it’s the tone engine

A consonant’s class exists for one reason: it decides the tone. Mid class is tonally neutral — every tone mark maps to exactly one tone. Here’s every outcome for ต as the initial:

Syllable– No mark◌่ mái èek◌้ mái thoo◌๊ mái trii◌๋ chattawa
Liveopen or sonorant endmidlowfallinghighrising
Deadstop end or short vowellowlowfalling——

Live syllable — open or sonorant end

–No markmid
◌่mái èeklow
◌้mái thoofalling
◌๊mái triihigh
◌๋chattawarising

Dead syllable — stop end or short vowel

–No marklow
◌่mái èeklow
◌้mái thoofalling

Change the initial to another class and the same marks produce different tones — that shift is what makes tone a small system, not 44 separate facts. Derive tones on the Tones surface →
