Word History

Etymology

Noun

Middle English, going back to Old English mūþ, going back to Germanic *munþa- (whence also Old Frisian mūth, mund "mouth," Old Saxon mūth, Middle Dutch mont, Old High German munt, Old Icelandic munnr, Gothic munþs), going back to dialectal Indo-European *mn̥t-, whence also Welsh mant "mouth, jaw, mandible," Latin mentum "chin"

Note: This etymon is limited to Celtic, Italic, and Germanic, though a relation with Hittite mēni-, mēna- "face, cheek" has also been suggested. The form *mn̥t- has been taken as a verbal adjective of the base *men- (or *min-) seen in Latin ēminēre "to stick out, protrude," but apparently nowhere else in Indo-European (see minatory).

Verb

Middle English mouthen, derivative of mouth mouth entry 1
