Uncleanly → It is formed from "un-" (meaning not) and "clean" (from Old English *clæne*, meaning free from dirt or impurities) and the suffix "-ly" (meaning in a manner of). The word "uncleanly" means in a manner that is not clean or free from dirt.
Think of 'not' ('un-') being added to 'clean' — this helps you remember that 'uncleanly' means not clean.
