FOURLETTERWORD
Four-letter word
The phrase four-letter word refers to a set of English-language words written with four letters which are considered profane, including common popular or slang terms for excretory functions, sexual activity and genitalia, and sometimes also certain terms relating to Hell and/or damnation when used outside their original religious context, and/or slurs. The "four-letter" claim refers to the fact that a large number of English "swear words" are incidentally four-character monosyllables. This description came into use during the first half of the twentieth century.The above text is a snippet from Wikipedia: Four-letter word
