The word implore is often used to describe an urgent request made out of desperation. A man on death row might implore the governor to grant him a last-minute pardon. In the old days, you might have heard the word spoken by someone with lousy aim at a duel — "I implore you not to shoot me, my good man!" Today, this first-person use of the word sounds old-fashioned, although you might still hear it in a period drama.
