Questions (preguntas) are sentences used to obtain specific information. They are always used with question marks (¿…?). Spanish has two main types of questions: closed questions and information questions.

Closed questions are those that can be answered with a simple affirmative (sí) or negative (no) word. Spanish closed questions can have the same form as statements and be distinguished by simply changing the intonation in speech (to a rising intonation) or adding question marks in writing. However, it is also possible to switch the place of the verb and the subject (if it is expressed). For example:

Information questions ask for specific pieces of information and cannot be answered with a simple "sí" or "no". These questions start with an interrogative word (like Qué, Quién(es), Cuál(es), Cuánto(s)/a(s), Dónde, Cómo, Cuándo etc.), followed by the verb and then the subject (if it is expressed). Keep in mind that, unlike yes/no questions, the inversion of the verb and the explicit subject is obligatory here. Take a look at some examples:
