legume (n.) Look up legume at Dictionary.com
plant of the group of the pulse family, pea, 1670s, from French légume (16c.), from Latin legumen "pulse, leguminous plant," of unknown origin. One suggestion ties it to Latin legere "to gather" (see lecture (n.)), because they can be scooped by the handful. Middle English had the word in the Latin form legumen (late 14c.).
