Latin Small Letter Z with Curl

Latin Small Letter Z with Curl at U+0291 represents the voiced alveolo-palatal fricative used in phonetic transcription, a sound like a “z” articulated with the tongue body raised toward the palate. It belongs to the IPA Extensions block and is mainly a specialist letter rather than a character used in ordinary spelling. Its central use is in the International Phonetic Alphabet. Linguists use it to transcribe sounds found in languages such as Mandarin, Polish, and Russian-like palatalized environments, for example in analyses where a contrast is made between plain z, postalveolar sounds, and the more fronted alveolo-palatal ʑ. The character also appears in language-learning materials, dictionaries, phonology papers, and fieldwork notes when precise pronunciation matters. In romanization discussions it may be used to explain what a spelling or transliteration represents, especially for languages whose writing systems do not directly show the phonetic distinction. Because it is shaped like a small z with a lower curl, it can be confused at a glance with plain z or similar phonetic letters in small type. Searching for it may not match ordinary “z,” so phonetic databases and academic texts often treat it as a distinct symbol.
