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

A consonant’s class exists for one reason: it decides the tone. Low class is the shifted class — the same mark lands a different tone than on mid or high. Here’s every outcome for ย as the initial:

Syllable– No mark◌่ mái èek◌้ mái thoo
Liveopen or sonorant endmidfallinghigh
Dead · longlong vowel + stopfallingfallinghigh
Dead · shortshort vowel + stophighfallinghigh

Live syllable — open or sonorant end

–No markmid
◌่mái èekfalling
◌้mái thoohigh

Dead · long syllable — long vowel + stop

–No markfalling
◌่mái èekfalling
◌้mái thoohigh

Dead · short syllable — short vowel + stop

–No markhigh
◌่mái èekfalling
◌้mái thoohigh

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 →
