'antipole' originates from a combination of the Greek prefix 'anti-' (from Greek 'anti', meaning 'against, opposite') and the English word 'pole' (ultimately from Greek 'polos' meaning 'axis' via Latin 'polus').

'antipole' was formed in Modern English by combining the prefix 'anti-' with 'pole'; 'pole' entered English via Latin 'polus' and Greek 'polos' and has been used to denote an axis or extremity since Old English/Medieval periods.

Initially it meant 'an opposite pole' (a literal opposite end or point), and over time it has retained that basic sense, remaining a relatively rare/specialized term.
