'unapologetically' originates from the prefix 'un-' meaning 'not' and the word 'apologetic,' which comes from the Greek word 'apologia,' meaning 'a speech in defense.'

'apologia' transformed into the English word 'apologetic,' and eventually became 'unapologetically' with the addition of the prefix 'un-' and the suffix '-ally.'

Initially, it meant 'not expressing regret,' and this meaning has largely remained the same in modern usage.
