Forming questions (intonation and question words)

What does "forming questions (intonation and question words)" mean in Spanish?

Spanish uses two basic ways to make direct questions:

- Intonation (yes/no questions). You keep the normal word order and change the voice to ask for confirmation: "Vienes mañana." → "¿Vienes mañana?" (Are you coming tomorrow?).
- Question words (open or wh-questions). You add a question word such as qué, quién, dónde, por qué, cómo, cuánto, etc., to ask for specific information: "¿Dónde vives?" (Where do you live?).

Two important writing rules in Spanish:

- Every direct question must begin with an inverted question mark (¿) and end with a normal question mark (?). Example: ¿Qué hora es?
- Interrogative words carry an accent mark when they are used in questions or exclamations: qué, quién, dónde, cuándo, cómo, cuánto, por qué, cuál.

When do I use intonation (yes/no questions)?

Use intonation when you expect a yes/no answer or when you want confirmation. In spoken Spanish you simply raise your pitch at the end of the sentence; in writing you mark it with question marks.

How the sentence looks

- Word order often stays the same as a statement: Subject + Verb + Object or Verb + Object + (optional subject). Spanish often drops the subject pronoun.
- Example (statement): "Tú tienes la llave." (You have the key.)
- Same with intonation (question): "¿Tú tienes la llave?" or more naturally "¿Tienes la llave?" (Do you have the key?)

Examples

- "¿Vienes mañana?" — Are you coming tomorrow?
- "¿Tienes tiempo ahora?" — Do you have time now?
- "¿Has comido?" — Have you eaten?
- "¿Quieres café?" — Do you want coffee?
- "¿No vienes?" — You aren’t coming, are you? (negative confirmation)

Notes about intonation in speech

- Yes/no questions usually have rising intonation at the end.
- Wh-questions (with question words) usually have a falling intonation because they are open questions asking for information.

How are questions written (punctuation and accents)?

- Opening inverted question mark (¿) + closing question mark (?). Example: ¿Dónde está el baño?
- Interrogative words always have accents in direct questions: qué, quién(es), cuál(es), dónde, cuándo, cómo, cuánto(a/os/as), por qué.
- Do not confuse these with the same words without accents when used as conjunctions or pronouns in non-question contexts: "que" (that), "como" (like/as), "cuando" (when as a conjunction).

Tag questions and confirmations

To ask for confirmation you can add short tags at the end:

- "¿no?" — "Vienes, ¿no?" (You’re coming, aren’t you?)
- "¿verdad?" — "Eres Ana, ¿verdad?" (You’re Ana, right?)
- "¿no es así?" — "Esto es difícil, ¿no es así?" (This is difficult, isn’t it?)

These are common and often use neutral falling or rising intonation depending on emphasis.

When and how do I use question words (qué, quién, dónde, etc.)?

Question words (wh-words) ask for specific information. They usually appear at the beginning of the question and are followed by the verb; the subject can be explicit or omitted.

Common question words and examples

- qué — what (definition, identity, or before a noun)
- "¿Qué quieres?" — What do you want?
- "¿Qué libro compraste?" — Which/what book did you buy?
- "¿Qué es eso?" — What is that?

- cuál / cuáles — which, which one(s) (choice from a set)
- "¿Cuál es tu número de teléfono?" — What is your phone number? (choice/identification)
- "¿Cuál de estos prefieres?" — Which of these do you prefer?

- quién / quiénes — who (person or people)
- "¿Quién llamó?" — Who called?
- "¿Quiénes vienen mañana?" — Who is coming tomorrow?
- With direct objects: "¿A quién viste?" — Who did you see? (note the preposition a)

- cuánto / cuánta / cuántos / cuántas — how much / how many (agree in gender & number with the noun)
- "¿Cuánto cuesta?" — How much does it cost?
- "¿Cuántas manzanas compraste?" — How many apples did you buy?
- "¿Cuánta agua bebes?" — How much water do you drink?

- dónde / adónde / de dónde — where / to where / from where
- "¿Dónde vives?" — Where do you live?
- "¿Adónde vas?" — Where are you going (to)? (movement to)
- "¿De dónde eres?" — Where are you from?

- cuándo — when
- "¿Cuándo es la reunión?" — When is the meeting?

- cómo — how / what (condition or manner)
- "¿Cómo estás?" — How are you?
- "¿Cómo lo hiciste?" — How did you do it?

- por qué — why (reason)
- "¿Por qué no viniste?" — Why didn’t you come?
- Answer: "Porque estaba enfermo." — Because I was sick.

- para qué — what for / for what purpose
- "¿Para qué estudias español?" — What are you studying Spanish for? (What’s the purpose?)

- con quién / a quién / de qué / en qué — prepositional question forms
- "¿Con quién saliste anoche?" — Who did you go out with last night?
- "¿En qué trabajas?" — What do you work in? / What is your job?
- "¿De qué hablaban?" — What were they talking about?

Qué vs. Cuál: how to choose

- Use qué to ask for a definition, description, or when the answer is a general explanation: "¿Qué es esto?" — What is this?
- Use cuál when you expect a choice, selection, or identification among possibilities: "¿Cuál prefieres?" — Which do you prefer?
- With the verb ser, both appear but often with different nuance:
- "¿Qué es esto?" — What is this? (asking for definition)
- "¿Cuál es tu nombre?" — What is your name? (identification/selection of a label)

Examples to compare:

- "¿Qué libro quieres?" — What kind of book / Which book (open question about the type)
- "¿Cuál de estos libros quieres?" — Which one of these books do you want? (selection from options)

Order: Where does the subject go in a question?

Typical order in wh-questions: Question word + Verb + (Subject) + Rest.

- "¿Dónde vive María?" — Where does María live?
- "¿Qué compraste (tú)?" — What did you buy (you)? (subject tú is optional and used for emphasis or clarity)

Spanish allows flexible word order for emphasis. Both of the following are correct, but emphasis differs:

- "¿Llegó Juan?" — Did Juan arrive?
- "¿Juan llegó?" — Did Juan arrive? (this version emphasizes "Juan")

Note about subject pronouns

Spanish often omits the subject pronoun because the verb form already shows the subject: "¿Llevas paraguas?" instead of "¿Tú llevas paraguas?"

Prepositions with question words and the personal "a"

- When the question word replaces a person who is the direct object, use the personal a: "¿A quién viste?" — Whom did you see?
- Prepositions usually stay before the question word: "¿Con quién vas?" — With whom are you going?
- If the preposition is part of the verb phrase, it appears with the question word: "¿En qué trabajas?" — In what do you work?

Adónde vs. Dónde vs. De dónde (movement vs location vs origin)

- adónde (a + dónde) — movement toward a place: "¿Adónde vas?" — Where are you going? (to)
- dónde — location: "¿Dónde estás?" — Where are you? (at)
- de dónde — origin: "¿De dónde vienes?" — Where do you come from?

Agreement: cuánto and gender/number

Cuánto behaves like an adjective and agrees with the noun:

- "¿Cuánto dinero tienes?" — How much money do you have? (cuánto - masculine singular)
- "¿Cuánta agua bebes?" — How much water do you drink? (cuánta - feminine singular)
- "¿Cuántos libros leíste?" — How many books did you read? (cuántos - masculine plural)
- "¿Cuántas preguntas hay?" — How many questions are there? (cuántas - feminine plural)

Politeness and formal questions

To be polite or formal, use conditional or more formal verb forms and usted:

- "¿Podrías ayudarme, por favor?" — Could you help me, please? (informal polite)
- "¿Podría usted decirme dónde está la estación?" — Could you tell me where the station is? (formal)
- Using conditional or subjunctive softens the request.

Indirect questions (brief note)

Indirect (embedded) questions do not use question marks and often start with verbs like "preguntar" or structures like "no sé" / "me pregunto":

- Direct: "¿Vendrás mañana?"
- Indirect: "Me pregunto si vendrás mañana." (I wonder whether you will come tomorrow.)

Common mistakes to avoid

- Forgetting the opening inverted question mark: "¿Qué haces?" — NOT "Que haces?".
- Missing accents on interrogative words: "que" vs "qué":
- Wrong: "Que quieres?" — Right: "¿Qué quieres?"
- Confusing qué and cuál:
- Wrong: "¿Qué es tu nombre?" — Better: "¿Cuál es tu nombre?" or "¿Cómo te llamas?"
- Incorrect agreement with cuánto:
- Wrong: "¿Cuánto manzanas compraste?" — Right: "¿Cuántas manzanas compraste?"
- Omitting the personal a with people (in some cases):
- More correct: "¿A quién viste?" instead of "¿Quién viste?" when you mean the object of the verb.
- Translating English word order directly:
- English: "Where you go?" (incorrect) — Spanish: "¿Adónde vas?" or "¿A dónde vas?"
- Mixing por qué / porque / porqué / por que:
- "¿Por qué no viniste?" (Why didn’t you come?)
- "No vine porque estaba enfermo." (I didn’t come because I was sick.)
- "No sé el porqué de esto." (I don’t know the reason for this.)

Glossary (short definitions)

- Intonation: The rise or fall in the voice when speaking. In Spanish, intonation helps mark yes/no questions.
- Question word (wh-word): Words that begin an open question: qué, quién, dónde, cuándo, cómo, por qué, cuánto, cuál, etc.
- Personal a: The preposition "a" used before a direct object that is a person: "¿A quién viste?"
- Agreement: Matching gender and number (as with "cuánto/cuánta/cuántos/cuántas").
- Indirect question: A question embedded in a larger sentence, not written with question marks: "No sé cuándo viene."

Final tips for learners

- Practice listening for the rising intonation of yes/no questions and the falling intonation of wh-questions.
- Always use inverted question marks in writing and put accents on interrogative words.
- Learn common question words and practice forming short questions aloud: it will help internalize word order and intonation.
- When in doubt, use the verb + subject order (¿Llega Marta?) and include the question word at the start for wh-questions (¿Qué, Quién, Dónde...).

With many examples and regular practice, forming questions by intonation and using question words will become natural. Remember: Spanish is flexible with word order, but punctuation and accents are strict in writing.
