'answerability' originates from the word 'answerable,' which is derived from the Old English word 'andswarian,' meaning 'to answer.'

'andswarian' transformed into the Middle English word 'answere,' and eventually became the modern English word 'answerable,' leading to the noun form 'answerability.'

Initially, it meant 'to respond or reply,' but over time it evolved into its current meaning of 'being accountable or responsible.'
