noun important European leguminous forage plant with trifoliate leaves and blue-violet flowers grown widely as a pasture and hay crop
originFrom French Lucerne, known in Swiss German as Lozärn, from Medieval Latin Lucernense, Luciaria, Lucerna, of uncertain origin, but possibly from Latin lūcĭus (“pike”) with the suffix -ārĭa, as in "place with a large number of pike." Popular etymology associated it with lucerna (“lantern”), though both words are related to lux (“light”). Also compare Leodegar, Burgundian bishop of Autun.
