What’s the difference between Que and queue?

Cue typically refers to a signal that encourages someone to take an action, while queue indicates an ordered line or file. Both cue and queue are pronounced like the letter Q, and are considered to be homophones. Homophones are words that sound the same but have different meanings.

Why is the word queue so weird?

It has to do with some of the different rules of French pronunciation and spelling. The word is French, it means tail. In French, Q and U are usually paired, as they are in English, but they make just a K sound rather than a KW sound. The EU is the vowel sound of this word.
