agony

In Ancient Greece, a public gathering was called agon. Since the Greeks placed a high value on sports and athletic competition, there were almost always athletic events at gatherings on festival days. The struggle to win the prize in such contests came to be called agonia. This term came also to be used for any difficult physical struggle and then for the pain that went with it—physical or mental. Our English word agony, meaning “intense pain of mind or body,” thus comes from a word that meant a happy celebration.
