Voiceless upper-pharyngeal plosive

Summary

A voiceless upper-pharyngeal plosive or stop is a rare consonant. No language is known to have a phonemic upper pharyngeal plosive. The Nǁng language (Nǀuu) is claimed to have an upper pharyngeal place of articulation among its click consonants— clicks in Nǁng have a rear closure that is said to vary between uvular or upper pharyngeal, depending on the click type. However, if the place were truly pharyngeal, they could not occur as nasal clicks, which they do.
