Gha

Φ φ
The letter Ƣ (minuscule: ƣ), called gha, was used in the Latinorthographies of various, mostly Turkic languages, as part of the early Soviet Jaꞑalif orthographies. It was also later included in the Chinese pinyin-based alphabets for Kazakh and Uyghur until 1983. It usually represents a voiced velar fricative[ɣ] but is sometimes used for a voiced uvular fricative[ʁ]. All orthographies that used the letter have been phased out.
Historically, it is derived from a handwritten form of the small Latin letter ⟨q⟩ around 1900. The majuscule is then based on the minuscule. Its use for [ɣ] stems from the linguistic tradition of representing such sounds (and similar ones) by q in Turkic languages and in transcriptions of Arabic or Persian (compare kaf and qaf).
