gymnast comes from Greek gymnastēs ('trainer of athletes'), from gymnázein ('to train, exercise naked'), from gymnós ('naked'). The path is chiefly one of transmission: the word passes through the named languages and forms, with each stage preserving part of the modern shape. In present English, the noun sense is "a person trained in gymnastics", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as gymnasium, and in derivatives such as gymnastic and gymnastics. Its semantic neighborhood includes acrobat, tumbler, and athlete, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Ancient Greek gymnastēs and Ancient Greek gymnós.
