What does mandibulate mean?
Mandibulate means to chew or grind with the jaws. It can describe an ordinary action, such as an animal working food between its teeth, but the word is also used in technical contexts for movement or articulation of the mandible, the lower jawbone. Its uncommon sound and precise jaw-related meaning make it useful in anatomy, dentistry, zoology, and descriptions of feeding mechanics. In ordinary conversation, “chew” or “masticate” will usually sound more natural. Mandibulate derives from the Latin mandibula, meaning “jaw,” which also gives English the words mandible and mandibular. The related noun mandibulation can refer either to the act of chewing or, in dentistry, to the functional movement of the lower jaw.
