'incorrectly-modified' originates from the combination of 'incorrectly' and 'modified'. 'Incorrectly' comes from the Latin 'incorrectus', meaning 'not corrected', and 'modified' comes from the Latin 'modificare', meaning 'to measure or limit'.

'incorrectly-modified' evolved from the combination of 'incorrectly' and 'modified', which were used separately in Middle English and later combined in modern English.

Initially, 'incorrectly-modified' meant 'changed in a wrong way', and this meaning has largely remained the same in modern usage.
