阿布哈茲語
In the alphabets of Abaza, Adyghe, Avar, Dargwa, Ingush, Lak, Lezgian, and Tabassaran, it is a modifier letter which signals the preceding consonant as an ejective or aspirated consonant; this letter has no phonetic value on its own. An exception is the Abkhaz language, which does not use the palochka for rendering aspiration, but instead uses the schwa (ә) as a modifier letter for labialization.
