The most common usage of queue refers to a waiting line of persons or vehicles. Example: "Paul looked at the
long queue and decided to go and rent a movie instead." The verb form refers to getting in line, to queue up for something.
Another contemporary sense of queue refers to a sequence of messages held in storage awaiting transmission on a computer.
The original meaning of the word queue, however, was a braid of hair worn hanging at the back of the head. The
French word for tail, queue appeared in English in the 18th century. The original root was the Latin cauda.
Cauda was also the source of the Italian word coda which was adapted into English as a musical term. The tail end of
a movement or composition is a coda.
