'unamended' originates from the prefix 'un-' meaning 'not' and the verb 'amend' from Latin 'emendare', where 'e-' meant 'out' and 'mendare' meant 'to correct'.

'amend' changed from the Latin word 'emendare' and eventually became the modern English word 'amend'.

Initially, 'amend' meant 'to correct or improve', and 'unamended' has retained the meaning of 'not corrected or improved'.
