The only common Spanish word that starts with "q" is "que". This word means "that" or "which" and is used in many different grammatical contexts.
There are a few less common words that start with "q":
* "qui": This is a very formal way to say "who." It's rarely used in everyday speech.
* "quórum": This is a loanword from English, meaning "quorum."
You will also find "q" in words that are part of proper nouns, like "Quito" (the capital of Ecuador) or "Qatar."
Because of its rarity, it is important to remember that the "q" in Spanish is always followed by a "u" and pronounced with a /k/ sound.
