to recover it; to retrieve it“De recuperá” is not normally complete by itself. It is the beginning of “de recuperá-lo” or another form with an attached pronoun, where the infinitive recuperar loses the final -r and receives an accent: recuperá-lo. Without an attached pronoun, use “de recuperar.”
PO: Então, achou uma forma de recuperá-lo, às custas do pobre menino.
EN: Then he found a way to recover it, at the poor boy’s expense.
