'acyrological' originates from Greek, specifically the word 'akyrologia,' where 'a-' meant 'not' and 'kyros' meant 'authority' or 'power,' combined with 'logos' meaning 'word.'

'akyrologia' transformed into the English word 'acyrological' through Latin influence.

Initially, it meant 'incorrect use of words,' and this meaning has largely remained the same in modern usage.
