'problem-solving' originates from the combination of 'problem' and 'solve,' where 'problem' comes from the Greek word 'problēma,' meaning 'a question proposed for solution,' and 'solve' comes from the Latin word 'solvere,' meaning 'to loosen or untie.'

'problem-solving' evolved from the combination of the words 'problem' and 'solve' in English, maintaining their original meanings.

Initially, it meant 'finding a solution to a problem,' and this meaning has largely remained the same in modern usage.
