Unholiest → It is formed from "un-" (meaning not) and "holy" (from Old English *halig*, meaning sacred or consecrated) and the superlative suffix "-est" (indicating the highest degree). The word "unholiest" means the most not sacred or the most profane.
Think of 'not sacred' ('un-') and 'holy' to remember that 'unholiest' refers to something that is the most profane or lacking in holiness.
