Plural of bilabial; consonant sounds that are produced by closing or pressing both lips together.
From bilabial (Latin 'bi-' two, 'labia' lips) plus English plural '-s'; the term categorizes a specific class of consonant sounds in linguistic phonetics.
Linguists discovered that bilabials like 'b' and 'p' are among the most universal sounds across human languages—perhaps because our lips are the easiest articulators we have.
