Forming Questions in Spanish

By Eric W. Vogt

This lesson begins with the structure of declarative or indicative statements in Spanish, then shows the three ways of turning them into questions. It also explains the punctuation and the pronunciation of questions vs. statements in terms of rising or falling intonation.

Building A Question

In order to form a question in Spanish, you must first be familiar with how statements are structured. Let’s build a Spanish sentence together. Most sentences begin with the subject, or doer of the action. For our sentence, let’s pick Juan y Tomás as the third-person plural subject (= ellos). Next, we need an action. Let’s pick something very easy, like nadar (to swim). Of course, we have to conjugate this infinitive form so that it agrees with the subject, so the form is nadan. Now we have Ellos nadanJohn and Thomas (or they) swim. This is a simple, declarative sentence, indicating an action. In fact, this present tense is called the present indicative because that is what verbs in this tense do – they simply declare or point out the actions done by subjects. In speech, both English and Spanish tend to end a statement with a slightly falling tone.

Questions also use this tense to find out about the actions performed (or not) by subjects.How would you turn the statement above into a question? That is, how would you ask someone if John and Thomas were performing or could perform the action of swimming? One simple way would be to ask Do they swim? Before we proceed to learn how to form the question in Spanish, you need to focus on two things about this question in English. First, the question marker, or word that cues the listener that a question is coming, is do. It has other forms too (did, don’t, doesn’t and so forth). Interestingly, English is the only Indo-European language that uses a particular verb to introduce questions. The second thing to notice is that the subject appears after this question-making verb.

Different Forms

In addition to having specific interrogative words equivalent to the English interrogatives such as Who?, Where? and When?, there are three ways to form a question in Spanish. One way is to invert the order of subject and verb. Our declarative or indicative statement Ellos nadan can become a question simply by saying ¿Nadan ellos? In writing, the question is marked at the beginning with the upside-down question mark and closed just as in English with the right-side up one. In speaking, also as in English, the voice tends to rise at the end of a question.

Another way to turn the statement into a question in Spanish is to simply use the rising tone without changing the word order: ¿Ellos nadan? This method of question formation can create a tone of incredulity or even sarcasm.

Finally, there is the tag question. A tag question is one that makes a statement and follows up with a quick question, almost like an afterthought. The most common tags are ¿no? and ¿verdad? In writing, the tag question is Ellos nadan, ¿no? Notice the way in which the statement is separated from the tag question by a comma and that the question only is framed with the written question marks. With tag questions, the initial statement is still stated as a declarative, that is, with a slightly falling tone as the word nadan is pronounced. The tag question ¿no? is pronounced with a rising tone.

The quizzes to this lesson will present you with statements which you are to convert into two kinds of questions: the first type, inverting subject and verb, and the tag questions. The option of simply pronouncing the statement as a question cannot really be tested in writing except for framing it with the question marks!
