'anti-patriotism' originates from Greek and French/Latin elements: the prefix 'anti-' from Greek 'anti-' meaning 'against', combined with 'patriotism', which comes (via French 'patriotisme' and Latin/Greek roots) from 'patriota'/'patria' referring to 'fatherland' or 'country'.

'patriotism' entered English via French 'patriotisme' (from Latin/Greek roots meaning 'of one's fathers' or 'fatherland'); the prefix 'anti-' (Greek) was attached in modern English to form 'anti-patriotism' to denote opposition to that concept.

Initially the components referred simply to 'against' + 'love of country'; over time 'anti-patriotism' has come to denote both a personal lack of patriotic feeling and explicit ideological critique of nationalism and patriotic sentiment.
