render: [14] Latin reddere meant ‘give back’. It was a compound verb formed from the prefix re- ‘back’ and dāre ‘give’ (source of English date, donate, etc). In Vulgar Latin this was changed to *rendere, perhaps under the influence of prendere ‘take’, which passed into English via Old French rendre. Rent ‘payment’ goes back to the past participle of *rendere. => date, donate, rent[render etymology, render origin, 英语词源]
