αγωνία

Etymology: From Ancient Greek ἀγωνία (agōnia), meaning 'struggle for victory, anxiety'. Originally referred to the mental and physical strain of athletes before competitions in ancient Greek games. The word shares the same root 'αγών' (contest, struggle) that gives us English words like 'agony', 'antagonist', and 'protagonist'. The semantic evolution from 'athletic contest' to 'mental distress' reflects how pre-competition nervousness became associated with general anxiety.
