tender (adj.): "soft, easily injured," early 13c., from Old French tendre "soft, delicate; young" (11c.), from Latin tenerem (nominative tener) "soft, delicate; of tender age, youthful," from a derivative of PIE root *ten- "stretch" (see tenet), on the notion of "stretched," hence "thin," hence "weak" or "young." Compare Sanskrit tarunah "young, tender," Greek teren "tender, delicate," Armenian t'arm "young, fresh, green."

Meaning "kind, affectionate, loving" first recorded early 14c. Meaning "having the delicacy of youth, immature" is attested in English from early 14c. Related: Tenderly; tenderness. Tender-hearted first recorded 1530s.
