'unpatriotic' originates from the prefix 'un-' meaning 'not' and 'patriotic,' which comes from the Greek word 'patriōtikos,' meaning 'of one's fatherland.'

'patriotic' evolved from the Greek word 'patriōtikos' through Latin 'patrioticus' and eventually became the modern English word 'patriotic.' The prefix 'un-' was added to form 'unpatriotic.'

Initially, 'patriotic' meant 'of one's fatherland,' and 'unpatriotic' has consistently meant 'not having devotion to one's country.'
