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

A consonant’s class exists for one reason: it decides the tone. High class + no mark on a live syllable = rising tone; it reaches tones the low twins can't. Here’s every outcome for ห as the initial:

Syllable– No mark◌่ mái èek◌้ mái thoo
Liveopen or sonorant endrisinglowfalling
Deadstop end or short vowellowlow—

Live syllable — open or sonorant end

–No markrising
◌่mái èeklow
◌้mái thoofalling

Dead syllable — stop end or short vowel

–No marklow
◌่mái èeklow

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 →
