Meaning

noun perennial aromatic herbs growing in hedgerows or scrub or open woodlands from western Europe to central Asia and in North America

originFrom French calament (assimilated in English to mint), from Old French calament, calamente, from Medieval Latin calamentum, from Latin calaminthe, from Ancient Greek καλαμίνθη (kalamínthē, “an odoriferous plant”), of uncertain origin (either by haplology from *καλαμο-μίνθη (*kalamo-mínthē) or a loanword, which Beekes considers most likely to be from Pre-Greek). Attested since early 17th century.
