ɧ is defined as ‘simultaneous ʃ and x’ in IPA, and its existence in Swedish is widely attested. This article provides a detailed description of a [ɧ]-like sound attested in Amdo Tibetan (Tibetic, Tibeto-Burman) and defines the symbol ɧ in Amdo Tibetan as ‘simultaneous ɕ and x’. It then uses the synchronic and diachronic perspectives to present the necessity of using the symbol /ɧ/ in the phonology. The article further explores a sound correspondence between /ɧh/ and a Literary Tibetan sh simple initial and its typological aspect through a comparison with several Khams Tibetan dialects.
