Word Originlate 15th cent. (denoting a type of clover or trefoil, described by Homer as food for horses): via Latin from Greek lōtos, of Semitic origin. The term was used by classical writers to denote various trees and plants; the legendary plant (sense (3)), mentioned by Homer, was thought by later Greek writers to be Ziziphus lotus, a relative of the jujube plant found in Eurasia.
