'incorrectly-solved' originates from the combination of 'incorrectly' and 'solved', where 'incorrectly' is derived from 'incorrect', meaning 'not correct', and 'solved' is the past participle of 'solve', meaning 'to find an answer'.

'incorrectly' changed from the Old French word 'incorrigible' and eventually became the modern English word 'incorrectly'. 'Solved' comes from the Latin word 'solvere', meaning 'to loosen or untie'.

Initially, 'incorrectly' meant 'not correct', and 'solved' meant 'to find an answer'. Together, they describe a solution that is not correct.
