mid-13c., from Old English hunigsuge, meaning perhaps honeysuckle, clover, or privet, literally "honey-suck" (see honey (n.) + suck) + diminutive suffix -el (2). So called because "honey" can be sucked from it. In Middle English sometimes a confused rendering of Latin locusta, taken as the name of a plant.[honeysuckle etymology, honeysuckle origin, 英语词源]
