I want to know the answer to the following question:
What Greek word did gymnastics derive from?
All the background I'm provided with is that "The word gymnastics derives from the common Greek adjective γυμνός (gymnos) meaning "naked", by way of the related verb γυμνάζω (gymnazo), whose meaning is to train naked", "train in gymnastic exercise", generally "to train, to exercise".". Is that enough to answer the question?
