Questions: Complete Guide

Spanish questions are built on a handful of clear rules: inverted question marks, obligatory accents on question words, the qué vs cuál distinction, and a flexible but predictable word order. This master guide walks through the whole system so you can ask anything you need.

Yes/No Questions

A yes/no question expects an affirmative or negative answer. In Spanish, you form one in two ways.

By Intonation

The simplest option is to leave the sentence unchanged and use rising intonation at the end. This works in both speech and writing — in writing, the inverted question mark (¿) signals that the sentence is a question.

Compare with the statements Hablas inglés. / María está en casa. / Los niños terminaron la tarea. — the word order is identical; only the intonation and the question marks change.

By Inversion

Alternatively, you can place the subject after the verb, as in English. Both orders are correct and interchangeable.

The Inverted Question Mark

Spanish uses two question marks: an inverted ¿ at the start of the interrogative portion, and a regular ? at the end. The opening mark does not necessarily go at the start of the sentence — only at the start of the question.

See Yes/No Questions.

Question Words: Always Accented

Spanish interrogative words always carry a written accent, to distinguish them from their homophones that serve as relative pronouns or conjunctions. This accent is present in both direct and indirect questions.

The accent is not optional — spelling a question word without it is a genuine error.

Both sentences use qué with an accent, even though only the first has question marks.

Qué vs Cuál

This is the most subtle distinction among the question words, and the one that trips up English speakers most often. In English, both what and which translate to ambiguous territory.

Use qué for definitions and categories — when you want an answer that identifies the type, nature, or definition of something.

Use cuál/cuáles for selections — when there is an implicit set of options and you want the speaker to pick one.

Notice the last example: before a noun, Spanish almost always uses qué, not cuál. ¿Cuál libro? is grammatically possible but sounds regional or unusual.

See Qué and Cuál.

Quién / Quiénes

Quién asks about a person; quiénes is the plural. Both always carry an accent in questions and indirect questions.

In Spanish, prepositions must appear before the question word, not at the end of the sentence as in casual English. So Who are you waiting for? becomes ¿A quién esperás? — never ¿Quién esperás a?

See Quién.

Cuándo, Dónde, Adónde, De Dónde, Por Dónde

Cuándo asks about time.

Dónde asks about location (static).

Adónde (or a dónde) asks about destination — where to.

De dónde asks about origin — where from.

Por dónde asks about route — which way.

See Dónde and Cuándo.

Cómo

Cómo asks about manner, method, or quality. It also appears in common fixed expressions.

Beware the homophone como (without accent), which means as, like, since, how in non-question contexts.

See Cómo.

Por Qué vs Porque

This is perhaps the most commonly misspelled pair in Spanish. Four forms, four meanings.

The two everyday forms are por qué (asking why) and porque (answering because). Learn these first, and recognize porqué as a noun when you see it with an article.

See Por qué.

Cuánto / Cuánta / Cuántos / Cuántas

Cuánto asks about amount. It agrees with the noun it modifies in gender and number.

When used alone (as a pronoun), cuánto is usually masculine singular:

See Cuánto.

Tag Questions

A tag question tacks a small interrogative onto the end of a statement to ask for confirmation. The most common Spanish tags are ¿verdad? and ¿no?

Unlike English, Spanish uses the same tag regardless of the verb in the main clause. English has to pick from a dozen tags (isn't it? didn't you? weren't they?); Spanish just says ¿no? or ¿verdad?

See Tag Questions.

Indirect Questions

An indirect question is a question embedded inside another statement. In Spanish, indirect questions keep the accent on the question word but do not use question marks.

For yes/no indirect questions, use si (without accent):

Do not confuse this si (if) with sí (yes), which does have an accent.

Word Order in Questions

Spanish question word order is flexible, but there are some patterns.

With Question Words

When a question word appears, the verb usually comes immediately after it, and the subject (if expressed) goes at the end.

Subject Position

Subject pronouns are usually dropped because Spanish is a pro-drop language. When they are expressed, they often go at the end of the question for emphasis or clarity.

Prepositions Go to the Front

As noted earlier, a preposition must precede the question word — Spanish does not strand prepositions at the end of the clause.

Echo Questions and Confirmation

Spanish has a few colloquial question patterns that English lacks.

In Mexico, ¿Mande? is the standard polite way to ask someone to repeat themselves — saying ¿Qué? can seem abrupt.

Summary

1. Yes/no questions use intonation plus inverted question marks (¿?); there is no auxiliary like English do.
2. Subject inversion is optional: ¿Está María aquí? and ¿María está aquí? are both fine.
3. All question words (qué, cuál, quién, cuándo, dónde, cómo, por qué, cuánto) are accented — in both direct and indirect questions.
4. Qué asks for a definition or category; cuál asks for a selection from a set.
5. Before a noun, use qué, not cuál: ¿Qué libro leés?
6. Por qué (why, two words, accent) is the question; porque (because, one word, no accent) is the answer.
7. Cuánto agrees with its noun in gender and number.
8. Common tag questions: ¿verdad? and ¿no? — simpler than English, which varies the tag for each verb.
9. Indirect questions keep the accent on the question word but drop the question marks. Yes/no indirect questions use si (no accent).
10. Prepositions precede the question word: ¿Con quién? ¿De dónde? ¿Para qué?
