The Bengali letter Bengali: খ is derived from the Siddhaṃ, and is marked by the lack of a horizontal head line, unlike its Devanagari counterpart, Hindi: ख. The inherent vowel of Bengali consonant letters is /ɔ/, so the bare letter Bengali: খ will sometimes be transliterated as "kho" instead of "kha". Adding okar, the "o" vowel mark, Bengali: খো, gives a reading of /kho/.
Like all Indic consonants, Bengali: খ can be modified by marks to indicate another (or no) vowel than its inherent "a".
Bengali: খ is used as a basic consonant character in all of the major Bengali script orthographies, including Bengali and Assamese.
Bengali Bengali: খ does not exhibit any irregular conjunct ligatures, beyond adding the standard trailing forms of Bengali: ব, Bengali: য ya-phala, and Bengali: র ra-phala, and the leading repha form of Bengali: র.[1]
