Questions & Answers about ¿Quién escribe la carta?
Why does quién have an accent mark on the "e"?
In Spanish, all question words—like quién (who), cómo (how), and dónde (where)—always carry an accent mark. This tells you it is a question word, distinguishing it from the same word used in normal statements (like saying "the person who wrote this").
How do I know which form of the verb to use after quién?
What if I think multiple people are writing the letter?
Spanish has a plural form for "who"! If you expect the answer to be a group of people, you change the question word to quiénes and use the "they" form of the verb: ¿Quiénes escriben la carta?
Do I always need to use the upside-down question mark (¿)?
Yes, in written Spanish, every question must start with an inverted question mark (¿) and end with a standard one (?). Because Spanish doesn't always change word order to make a question like English does, this symbol lets you know a question is starting right away.
