The voiceless postalveolar affricate is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is [tʃ], and the equivalent X-SAMPA symbol is [tS]. Alternatives commonly used in linguistic works, particularly in older or American literature, are č and more rarely tš.
Historically, this sound often derives from a former voiceless velar plosive (k, as in English, Mandarin Chinese, and Romance languages) or voiceless dental plosive (t, as in Japanese) by way of palatalization, especially next to a front vowel.
