'answer' originates from Old English, specifically the word 'andswaru,' where 'and-' meant 'against' and 'swaru' meant 'affirmation.'

'andswaru' transformed into the Middle English word 'answere,' and eventually became the modern English word 'answer.'

Initially, it meant 'a sworn statement,' but over time it evolved into its current meaning of 'a response to a question or problem.'
