¿ ?

1. encloses a question in Spanish; equivalent in English and many other languages: ?

   ¿Cómo estás? ― How are you?

   Si tú fuiste, ¿a qué hora llegaste? ― If you went, at what time did you arrive?

• In written Spanish, the ⟨¿⟩ mark is placed at the beginning of an interrogative phrase, with the ⟨?⟩ at the end of the phrase. As SMS messaging and other forms of electronic communication have become more common, many speakers only use ⟨?⟩ for questions and ⟨!⟩ for exclamations, leaving out the initial typographical mark. This is considered non-standard usage.
