'antitragic' originates from Modern English, specifically formed from the prefix 'anti-' (from Greek 'antí-' meaning 'against') combined with 'tragic' (from Greek 'tragikos').

'tragic' itself came into English via Latin 'tragicus' and Old French 'tragique' from Greek 'tragōidikos'/'tragikos'; 'antitragic' is a modern English compound created by prefixing 'anti-' to 'tragic'.

Initially it simply meant 'against or opposed to tragic elements', and over time it has been used to mean 'not tragic' or 'deliberately avoiding a tragic tone' in modern usage.
