'antipoetic' originates from Modern English, specifically formed from the prefix 'anti-' (from Greek 'anti-' meaning 'against') combined with 'poetic' (from Latin 'poeticus' via Old French 'poetique', ultimately from Greek 'poietikos').

'antipoetic' is a Modern English compound created from 'anti-' + 'poetic'; 'poetic' itself changed from Middle English/Old French forms such as 'poetique' and from Latin 'poeticus' (and before that Greek 'poietikos') to the modern English 'poetic'.

Initially the elements meant 'against' + 'relating to poetry'; over time the compound has come to mean 'not poetic' or 'opposed to poetic style', a sense consistent with its original components.
