A lot vs. Alot: 9 Grammatical Pitfalls
"soft, easily injured," early 13c., from Old French tendre "soft, delicate, tender" (11c.), from Latin tenerem (nominative tener) "soft, delicate, of tender age," from PIE *ten- "stretch" (see tenet). Meaning "kind, affectionate, loving" first recorded c.1300. Meaning "having the delicacy of youth, immature" is attested from early 14c. Tender-hearted first recorded 1530s.
"to offer formally," 1540s, from Middle French tendre "to offer, hold forth" (11c.), from Latin tendere "to stretch, extend" (see tenet). The retention of the ending of the French infinitive is unusual. The noun meaning "formal offer" is from 1540s; specific sense of "money that may be legally offered as payment" is from 1740.
"person who tends another," late 15c., probably an agent noun formed from Middle English tenden "attend to" (see tend (2)); later extended to locomotive engineers (1825) and barmen (1883). The meaning "small boat used to attend larger ones" first recorded 1670s.
