'properly' originates from Latin, specifically the word 'proprius,' meaning 'one's own' or 'special.' 'Answered' comes from Old English 'andswaru,' meaning 'a response or reply.'

'properly' evolved from Middle English 'properly,' while 'answered' evolved from Old English 'andswarian,' eventually becoming the modern English 'answer.'

Initially, 'properly' meant 'in a manner that is one's own,' but over time it evolved to mean 'correctly or appropriately.' 'Answered' has largely retained its original meaning of 'responded to.'
