Unhappy → It is formed from "un-" (meaning not) and "happy" (from Old English "hap", meaning luck or fortune). The word "unhappy" means not having luck or fortune, thus feeling sad or discontented.
Think of 'not' ('un-') being added to 'happy' — this helps you remember that 'unhappy' means not feeling happy.
