Uncouth → It is formed from "un-" (meaning not) and "couth" (from Old English *cūð*, meaning known or familiar). The word "uncouth" means not known or unfamiliar, often referring to someone who is awkward or lacking refinement.
Think of 'not known' ('un-') and 'familiar' ('cūð') to remember that 'uncouth' describes someone who is awkward or lacking in social grace.
