Ejective consonant

In phonetics, ejective consonants are voiceless consonants that are pronounced with simultaneous closure of the glottis. In the phonology of a particular language, ejectives may contrast with aspirated or tenuis consonants. Additionally, some languages have sonorants with creaky voice that pattern with ejectives while other languages have ejectives that pattern with implosives—this has led to phonologists positing a phonological class of glottalized consonants (see glottalic consonant and below for further discussion).
