Unfriendly → It is formed from "un-" (meaning not) and "friendly" (from Old English "freond", meaning a person who loves or is fond of another). The word "unfriendly" means not friendly or lacking in kindness or warmth.
Think of 'not' ('un-') being added to 'friendly' — this helps you remember that 'unfriendly' describes someone who is not kind or warm.
