The word 'tender' entered English in the early 13th century from the Old French 'tendre,' meaning soft, delicate, or young. This Old French term originated from the Latin 'tener,' which carried the same meanings of delicate, soft, and youthful. The Latin 'tener' is traced back to the Proto-Indo-European root ten- meaning "to stretch," a concept linked to pliability and flexibility, hence softness. The verb sense, "to offer," emerged in the mid-16th century as a specialized use from the Old French 'tendre' meaning "to offer, hold forth," which itself derived from the Latin 'tendere' ("to stretch, extend"). Thus, the seemingly disparate modern meanings—soft, painful, and to offer—are united by the ancient metaphorical logic of stretching something out, whether it be physical material, one's feelings, or a formal proposal.

The modern English word 'tender' is a simplex form derived from a single Latin root via Old French. Its multiple meanings stem from semantic branching from the core concept of "stretching" or "offering."
