ELI5: Why does the letter "U" almost always follow the letter "Q"?

Its called a digraph. Qu makes the /kw/ sound in the English language. You can thank Latin origins and the Greeks for that. There are a lot of words that have Q without a U after it, but they are mostly in Semitic languages.  Qatar, burqa, qabab.
