Blackhead → The word is formed from "black" (from Old English "blæc", meaning dark or without light) and "head" (from Old English "heafod", meaning the upper part of the body or the main part). A blackhead refers to a dark spot on the skin, often associated with clogged pores on the face.
Think of something that is 'dark' ('black') on the 'top' ('head') of the skin — that's why a blackhead is a dark spot on the skin.
