Dental (or more precisely denti-alveolar) clicks are a family of click consonants found, as constituents of words, only in Africa and in the Damin ritual jargon of Australia. In English, the tut-tut! (British spelling, "tutting") or tsk! tsk! (American spelling, "tsking") sound used to express disapproval or pity is an unreleased dental click, although it is not a lexical phoneme (a sound that distinguishes words) in English but a paralinguistic speech-sound. Similarly paralinguistic usage of dental clicks is made in certain other languages, but the meaning thereof differs widely between many of the languages (e.g., affirmation in Somali but negation in many varieties of Arabic).
