gymnasium (n.)
1590s, "place of exercise," from Latin gymnasium "school for gymnastics," from Greek gymnasion "public place where athletic exercises are practiced; gymnastics school," in plural, "bodily exercises," from gymnazein "to exercise or train," literally or figuratively, literally "to train naked," from gymnos "naked," from a metathesis of PIE *nogw-mo-, suffixed form of *nogw- "naked" (see naked).

A feature of all ancient Greek communities, at first it was merely an open space, later with extensive facilities and including training for the mind as well as the body. Hence its use in German from 15c. as a name for "high school" (more or less paralleling a sense also in Latin); in English it has remained purely athletic. For the "continental high school sense," English in 19c. sometimes used gymnastical as an adjective, gymnasiast for a student.

tuxedo (n.)

man's evening dress for semiformal occasions, 1889, named for Tuxedo Park, N.Y., a rural resort development for wealthy New Yorkers and site of a country club where it first was worn, supposedly in 1886. The name is an attractive subject for elaborate speculation, and connections with Algonquian words for "bear" or "wolf" were proposed. The authoritative Bright, however, says the tribe's name probably is originally a place name, perhaps Munsee Delaware (Algonquian) p'tuck-sepo "crooked river."

There was a hue and cry raised against the Tuxedo coat upon its first appearance because it was erroneously considered and widely written of as intended to displace the swallow tail. When the true import of the tailless dress coat came to be realized it was accepted promptly by swelldom, and now is widely recognized as one of the staple adjuncts of the jeunesse dorée. [Clothier and Furnisher, August 1889]
