'antipathetic' originates from Greek, specifically the word 'antipathēs', where 'anti-' meant 'against' and 'pathos' meant 'feeling'.

'antipathetic' changed from Late Latin 'antipathicus' and Middle French 'antipathétique', and eventually became the modern English word 'antipathetic' (the adverb formed by adding the suffix '-ally').

Initially, it meant 'having or showing feelings against (something)', and over time it evolved into the current sense of 'showing dislike or aversion'.
