'incorrectly-mended' originates from the combination of 'incorrectly' and 'mended', where 'incorrectly' is derived from Latin 'incorrectus', meaning 'not corrected', and 'mended' from Old English 'mendan', meaning 'to repair'.

'incorrectly' changed from the Latin word 'incorrectus' and 'mended' from the Old English 'mendan', eventually forming the modern English term 'incorrectly-mended'.

Initially, 'mend' meant 'to repair', and 'incorrectly' meant 'not corrected'. Together, they evolved to describe something repaired improperly.
