aromatic herb, plant of the genus Mentha, Old English minte (8c.), from West Germanic *minta (source also of Old Saxon minta, Middle Dutch mente, Old High German minza, German Minze), a borrowing from Latin menta, mentha "mint," itself from Greek minthē, personified as a nymph transformed into an herb by Proserpine, which is probably a loan-word from a lost Mediterranean language. For mint-julep, see julep.
