The
labial or
bilabial clicks are a family of
click consonants that sound something like a smack of the lips. They are found as
phonemes only in the small
Tuu language family (currently two languages, one moribund), in the
ǂHõã language of
Botswana (also moribund), and in the extinct
Damin ritual jargon of
Australia. However, bilabial clicks are found paralinguistically for a kiss in various languages, and as allophones of
labial–velar stops in some West African languages (Ladefoged 1968), as of /mw/ in some of the languages neighboring Shona, such as
Ndau and
Tonga.
