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 (depending on the listener/reader) sometimes also certain terms relating to Hell and/or damnation when used outside their original religious context(s), 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 euphemism came into use during the first half of the twentieth century.

Famous quotes containing the word word:
“We have good reason to believe that memories of early childhood do not persist in consciousness because of the absence or fragmentary character of language covering this period. Words serve as fixatives for mental images. . . . Even at the end of the second year of life when word tags exist for a number of objects in the child’s life, these words are discrete and do not yet bind together the parts of an experience or organize them in a way that can produce a coherent memory.”
—Selma H. Fraiberg (20th century)
