Etymology

The word "fake" likely originated from German fegen, meaning "to sweep" or "polish," which evolved metaphorically into "to deceive" (as in polishing a cheap object to make it appear valuable). By the 18th century, it entered English as slang for counterfeiting or trickery. The silent "e" is a common feature in English spelling but carries no meaning here.
