Is it que, queue, or q?

One of our persistent—and more puzzling—lookups is for the word que, which is entered in our dictionary (capitalized) as an abbreviation for Quebec. Qué is also a Spanish word that means “what.” That is not, however, the word that many people are looking for when they look up que in our dictionary. Que is homophonous with a number of other words, most of which have wildly different spellings and meanings. One of the words that people are looking for when they look up que is queue, a word that means “line” (as in, “We waited in the ticket queue.”) Sometimes people are looking for the homonym cue, or “a signal to start or do something” (“The lights just went out—that’s my cue to start the movie.”). Very occasionally, people look up que for coup, a word that refers to a violent and sudden overthrow or takeover of a government (“reports on the latest coup attempt”). And if you’re looking for the phonetic spelling of the letter q, try again: that’s cue.
