mentum n (genitive mentī); second declension[1]
Etymology
It is inherited from Proto-Italic *mn̥to-, inherited from Proto-Indo-European *mn̥-to- (“chin, mouth”), perhaps an old adjective “protruding” from a root *men- “to rise up, project” seen in ēmineō and prōmineō.[2][1][3] Cognate with Welsh mant (“mouth, jaw”), Gothic 𐌼𐌿𐌽𐌸𐍃 (munþs, “mouth”) and Old English mūþ (“mouth”).[2] Lewis and Short compare minae “threats”, originally “projections”.[4]
Earliest recorded meaning
De Vaan and Köbler date it from Plautus.[2][5] Köbler dates Plautus c. 250–184 BC.[5]
Semantic evolution
It was the chin of people and animals, and also the chin with its beard, as Cicero's statue of Hercules whose chin was a little worn by kisses.[3][4][6] The phrase mentum alicui tollere “to hold up someone's chin” meant to help someone out of trouble, a metaphor from swimming.[3] In architecture it was a projecting edge of a cornice, in Vitruvius.[3]
It survives in Italian mento, and a Vulgar Latin *mentōne gave French menton “chin”.[1] Zoology took English mentum for part of an insect's lower lip.[1]
