Nonexplosive stop
In phonetics and phonology, nonexplosive stops are a broad conception of consonants that resemble (and may include) implosives but that do not necessarily involve implosion or negative oral air pressure. These stop consonants lack the pressure buildup and burst release of pulmonic plosives, and include implosives, glottalized and laryngealized stops, as well as 'certain varieties of "lenis" and labial–velar stops'.
