This article is about the second letter of the Bengali alphabet. For a more general overview encompassing other Indic scripts, see Kha (Indic).
The Bengali letter খ is derived from the Siddhaṃ, and is marked by the lack of a horizontal head line, unlike its Devanagari counterpart, ख. The inherent vowel of Bengali consonant letters is /ɔ/, so the bare letter খ will sometimes be transliterated as "kho" instead of "kha". Adding okar, the "o" vowel mark, খো, gives a reading of /kho/.
Like all Indic consonants, খ can be modified by marks to indicate another (or no) vowel than its inherent "a".
খ in Bengali-using languages
খ is used as a basic consonant character in all of the major Bengali script orthographies, including Bengali and Assamese.
Conjuncts with খ
Bengali খ does not exhibit any irregular conjunct ligatures, beyond adding the standard trailing forms of ব, যya-phala, and রra-phala, and the leading repha form of র.[1]
