ห

ห • (hɔ̌ɔ)

1. hɔ̌ɔ hìip (ห หีบ), the 41st consonant letter of the Thai alphabet

• This letter belongs to the Thai high consonant class
• A silent, high-class ห "leads" low-class nasal stops (ง (ngɔɔ), ญ (yɔɔ), น (nɔɔ) and ม (mɔɔ)) and non-plosives (ว (wɔɔ), ย (yɔɔ), ร (rɔɔ) and ล (lɔɔ)), which have no corresponding high-class phonetic match, into the tone properties of a high-class consonant. In polysyllabic words, an initial mid- or high-class consonant with an implicit vowel similarly "leads" these same low-class consonants into the higher class tone rules, with the tone marker borne by the low-class consonant.
