means A line of people or things waiting their turn for something, or the act of forming such a line.

from From French queue, "tail," which descends from Latin cauda, also "tail." The image is wonderfully literal: a line of people trailing behind like an animal's tail. English borrowed it, and the British in particular took to both the word and the practice with great devotion. The four silent vowels stacked behind the lone Q are themselves a tiny queue — letters patiently waiting their turn to do nothing.
