Word Origin & History
gymnasium
1598, "place of exercise," from L. gymnasium "school for gymnastics," from Gk. gymnasion, from gymnazein "to exercise or train," lit. "to train naked," from gymnos "naked." Shortened form gym is attested from 1871. Introduced to Ger. 15c. as a name for "high school," in Eng. it has remained purely athletic. Gymnast (1594) in the modern sense is a back-formation of gymnastic, (1574) from Gk. gynmastikos "pertaining to or skilled in bodily exercise."
