gymnasium (English)

Where does "gymnasium" come from?

The English noun gymnasium was borrowed from Latin 'gymnasium'[1], which came from the Ancient Greek 'γυμνάσιον'[1][2] meaning 'exercise, school'[1][2][3]. This Greek term originated from the stem of 'γυμνάζω'[3] meaning 'to exercise'[3], which is built from 'γυμνός'[3][4] meaning 'naked'[1][2][3]. The Ancient Greek word reflects the historical practice of Greek athletes training naked[1][2]. Traced further back, 'γυμνός' derives from Proto Hellenic and ultimately from Proto-Indo-European root forms meaning 'naked'[5].
