'unorthographic' originates from the prefix 'un-' meaning 'not' and the word 'orthographic,' which comes from Greek 'orthographia,' where 'ortho-' meant 'correct' and 'graphia' meant 'writing.'

'orthographia' transformed into the Latin word 'orthographia,' and eventually became the modern English word 'orthographic,' with 'un-' added to form 'unorthographic.'

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