Etymology

Origin of tuxedo

1890–95, short for Tuxedo coat, after country club at Tuxedo Park, N.Y.

Explanation

Use the noun tuxedo to describe the dressy black suit that many men wear when they get married. It's not prom night without one of these formal jackets for men, which take their name from Tuxedo Park, New York, near New York City. The place name tuxedo, according to one line of etymological inquiry, is from an Algonquian word for "wolf," p'tuksit, while other scholars guess that it simply means "crooked river," p'tuck-sepo. Either way, a tuxedo today can also be called a dinner jacket or even the slangy "monkey suit," just for fun.
