Etymology

Origin of party

First recorded in 1250–1300; Middle English partie, paarty, from Old French, noun use of feminine of parti, past participle of partir “to divide, separate, go away,” from Latin partīre “to share, divide”; see part

Explanation

If you have a party, you invite people who will likely get along and like each other. If you join a political party, you choose the one whose members share your views. Party comes from part, which means "a division in the whole." You can see this in political parties: the groups that make up the whole of voters in a nation. Party also means "person or group," which we are reminded of at restaurants when asked, "How many are in your party?" This is how party as in "a social gathering" or as a verb — the act of enjoying yourself at such a gathering — came about.
