c. 1300, "to regain consciousness," from Anglo-French rekeverer (13c.), Old French recovrer "come back, return; regain health; procure, get again" (11c.), from Medieval Latin recuperare "to recover" (source of Spanish recobrar, Italian ricoverare; see recuperation). Meaning "to regain health or strength" is from early 14c.; sense of "to get (anything) back" is first attested mid-14c. Related: Recovered; recovering.
