Tongue click refers to a sharp, percussive sound produced when the tongue is used to create a rapid release of air inside the mouth. The sound results from forming a closure at one or more places inside the oral cavity—such as the alveolar ridge, palate, teeth, or sides of the tongue—and then releasing the constriction to produce a click.

Production details: A tongue click involves building up a seal at a chosen articulation point, creating a sealed chamber between the tongue and the roof of the mouth. Air pressure behind the seal is manipulated and released to generate the characteristic short, popping sound. Different places of articulation yield different types of clicks, and some clicks can be accompanied by voicing or nasalization in languages that use them phonemically.

Linguistic use: Clicks are phonemes in many southern African languages, notably Khoisan languages and some Bantu languages such as Xhosa and Zulu. In these languages, clicks can be independent consonants and may combine with vowels or other consonants, sometimes appearing in complex consonant clusters with various phonetic modifications.

Nonlinguistic and cultural use: Outside linguistic systems, tongue clicking is often used as a nonverbal cue—expressing disapproval, attracting attention, or serving as a rhythmic effect in music or performance. Perceived etiquette varies by culture; in some contexts, frequent tongue clicking can be considered rude or disruptive.

Health considerations: Repetitive or forceful clicking can irritate teeth or gums for some individuals, and persistent clicking accompanied by pain or functional issues may warrant medical or dental evaluation.
