Etymology: Grime began as a word for a face mask. Old English "grīma" meant a mask or disguise, and the same root lies behind the modern sense of dirt through a narrowing that happened in Middle English. The Middle English "grim" referred specifically to the dirt or soot that covered a person's face, so a grimy face was, in a sense, one that had acquired its own disguise. The shift from mask to dirt makes more sense once you see that soot and filth were the most visible thing a face could wear. Over time the sense spread from faces to any surface that collected a dark, clinging layer. Dialect forms in Dutch and Low German, such as "grijm" and "greme," meaning soot or dirt, seem to have reinforced this later meaning, and the English word's development was likely shaped by them.
