Why does the letter U almost always accompany the letter Q? The reason for this pairing is because QU is a digraph, which is a pair of letters that represents a single sound. In this case, it's "kw." Basically, the two are treated as a single character in the English language, mostly from borrowed words from Latin. Q's without U's aren't as common, but can be found in words like Iraq.
