'rightly-answered' originates from the combination of 'rightly,' meaning 'in a correct manner,' and 'answered,' the past participle of 'answer,' meaning 'to respond to a question or situation.'

'rightly' comes from Old English 'rihtlice,' and 'answered' comes from Old English 'andswarian,' which evolved into the modern English 'answer.'

Initially, 'rightly' meant 'in accordance with justice or law,' and 'answer' meant 'a response to a question.' Over time, 'rightly-answered' evolved to mean 'correctly responded to a question or situation.'
