What does labialize mean?
Labialize is a technical verb meaning to make a speech sound or pronunciation involve movement or rounding of the lips. Its use is most common in phonetics, phonology, linguistics, and speech therapy, where it describes the articulation of consonants and vowels and the visible or muscular actions involved in producing them. A speaker may labialize a sound by bringing the lips together, protruding them, or rounding them. The word is also used more broadly when discussing a change in pronunciation caused by the position of the lips. Because it names a specific articulatory process, labialize is more precise than the informal expression lip a sound, which may suggest simply forming a word with the mouth rather than describing a defined phonetic mechanism.

Where does labialize come from?
The word derives from Latin labium, meaning lip, combined with the suffix -ize, which forms verbs expressing an action or transformation. The related English adjective labial means relating to or formed by the lips, while bilabial describes consonants articulated with both lips. The development of labialize follows the usual pattern of -ize verbs: labial, meaning pertaining to the lips, was extended into a verb describing the production of a sound with lip movement.
