You have probably seen and used the expression s'il vous plaît—"please" many times. If translated literally, the phrase reads "if it pleases you." This construction sounds somewhat cumbersome, but it's a construction English speakers are familiar with in expressions such as "it pleases me greatly to introduce ..." (i.e., "I am pleased to introduce ... ") or "it pains me..."

Plaire is only used in the third person singular or plural and it is generally translated as "like," whereby the subject is expressed through the indirect object pronoun.
