Reversed glottal stop
The reversed glottal stop, ⟨ʕ⟩ (majuscule: , minuscule: , superscript: ˤ), is a letter of the Latin script. It is used to denote a voiced pharyngeal fricative and similar sounds, either as a caseless letter as in the International Phonetic Alphabet, or as a cased pair in the Pilagá alphabet.
