Although traditionally placed in the fricative row of the IPA chart, [ʕ] is usually an approximant. The IPA symbol itself is ambiguous, but no language is known to make a phonemic distinction between fricatives and approximants at this place of articulation. The approximant is sometimes specified as [ʕ̞] or as [ɑ̯], because it is the semivocalic equivalent of [ɑ].
Features
Features of the voiced pharyngeal approximant fricative:
Its manner of articulation varies between approximant and fricative, which means it is produced by narrowing the vocal tract at the place of articulation, but generally not enough to produce much turbulence in the airstream. Languages do not distinguish voiced fricatives from approximants produced in the throat.
Pharyngeal consonants are not widespread. Sometimes, a pharyngeal approximant develops from a uvular approximant. Many languages that have been described as having pharyngeal fricatives or approximants turn out on closer inspection to have epiglottal consonants instead. For example, the candidate /ʕ/ sound in Arabic and standard Hebrew (not modern Hebrew – Israelis generally pronounce this as a glottal stop) has been variously described as a voiced epiglottal fricative, an epiglottal approximant,[1] or a pharyngealizedglottal stop.[2]
