Aider → The word 'aider' comes from Old French 'aider', meaning to help or assist. It is derived from the Latin 'adiutare', which means to help or assist, formed from 'ad-' (meaning to) and 'iutare' (meaning to help). Thus, 'aider' means to provide help or assistance.
Think of 'aider' as someone who is 'helping' ('adiutare') another person — that's why 'aider' means to assist.
