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

'antipathēs' passed into Late Latin as 'antipathicus' and then into Medieval/Modern Latin and English, eventually forming the modern English adjective 'antipathic'.

Initially, it referred to 'having opposite or contrary feelings' (being opposed in feeling); over time it evolved to mean 'showing aversion or causing dislike' in modern usage.
