Borrowed verb meaning to please or satisfy

from Middle English plesen, plaisen, borrowed

Modern English
please

Around 1300, English borrowed Middle English plesen from Old French, carrying the older idea of making someone satisfied or agreeable. Its Latin ancestor, placeō, also appears in placebo: the word began as “I shall please” in the Vulgate phrase Placebo Domino, “I shall please the Lord,” before doctors adopted it for a treatment intended more to please than to cure. The legal word plea took a different-looking route from the same family: a “plea” was originally something agreed upon, then a decision, and finally an argument made in court. By the 1620s, please had been clipped from “if it please you,” turning a whole deferential sentence into one tiny verbal bow. So when a child says “please,” the word is carrying an ancient history of approval, negotiation, and—occasionally—trying to get someone to hand over the biscuits.
