Uncleaner → It is formed from "un-" (meaning not) and "clean" (from Old English *clæne*, meaning free from dirt or impurities) and the suffix "-er" (meaning one who). The word "uncleaner" refers to one who is not clean or makes something unclean.
Think of 'not' ('un-') and 'free from dirt' ('clean') — so an uncleaner is someone who is not clean.
