Lexical items containing both the letters “q” and “h” typically feature the digraph “qu,” representing the sound /kw/. Common examples include “question,” “quick,” and “quiet.” The “q” almost invariably precedes the “u” in English orthography, with rare exceptions like “suq,” a loanword from Arabic. This digraph originates from the Latin alphabet, which adapted it from Etruscan, ultimately tracing back to the Greek letter koppa (). The digraph simplifies spelling and pronunciation, representing a single phoneme efficiently.
The consistent pairing of “q” and “u” provides valuable information for readers and spellers. This predictable pattern facilitates efficient decoding of words and contributes to the standardization of English orthography. Understanding this relationship assists in language acquisition and promotes effective communication. Historically, this consistent spelling reflects the evolution of the language and the influence of Latin. It strengthens the structure and predictability of written English.
