Qué vs Cuál: Which Spanish Question Word to Use
¿Qué es tu nombre? sounds like a totally reasonable question if you’re translating “What is your name?” word for word — and it’s wrong. Native speakers say ¿Cuál es tu nombre? This single example trips up more English speakers than almost any other question-word mistake in Spanish, because English uses “what” so broadly that it doesn’t map cleanly onto qué and cuál.
The short version
- Qué asks for a definition or general information, or comes directly before a noun.
- Cuál asks someone to choose among options, even when there’s no visible list — asking for a name, a phone number, or a favorite counts as choosing from a set of possibilities.
When to use qué
- Asking for a definition: ¿Qué es esto? (What is this?) ¿Qué significa esa palabra? (What does that word mean?)
- Directly before a noun: ¿Qué libro leíste? (What book did you read?) ¿Qué hora es? (What time is it?) — qué is required here even where cuál would work in a similar English sentence.
- Asking someone to explain or clarify: ¿Qué quieres decir? (What do you mean?) ¿Qué pasó anoche? (What happened last night?)
When to use cuál
- Asking someone to pick from options, stated or implied: ¿Cuál prefieres? (Which one do you prefer?) ¿Cuál de los dos te gusta más? (Which of the two do you like more?)
- Asking for specific information like a name, date, address, or number — Spanish treats these as “selecting” the correct answer from many possibilities: ¿Cuál es tu dirección? (What’s your address?) ¿Cuál es la fecha de hoy? (What’s today’s date?)
- Followed directly by “es/son”: ¿Cuál es el problema? (What’s the problem?) ¿Cuáles son tus planes? (What are your plans?)
Quick chart
| Qué | Cuál |
|---|---|
| Definition — ¿Qué es la democracia? | Choice — ¿Cuál te gusta más? |
| Before a noun — ¿Qué color quieres? | Before “es/son” — ¿Cuál es tu color favorito? |
| General info — ¿Qué pasó? | Specific info — ¿Cuál es tu apellido? |
The rule behind the confusing cases
Here’s the pattern that clears up most of the confusion: qué is required immediately before a noun, no matter what. ¿Qué película viste? is correct — not ¿Cuál película viste?, even though “which movie” sounds like a cuál question in English. But when the question word is followed by a verb like “es” or “son” instead of a noun, cuál usually takes over, especially when there’s a specific answer being fished for: ¿Cuál es tu película favorita? (What’s your favorite movie?) The noun-vs-verb test settles almost every tricky case.
Cuáles: the plural you’ll need constantly
Cuál pluralizes to cuáles whenever the answer could involve more than one item — this trips learners up because qué never changes form, so they sometimes forget cuál does. ¿Cuáles son tus colores favoritos? (What are your favorite colors?) asks for possibly several answers, so it needs the plural. Compare that to a single expected answer: ¿Cuál es tu color favorito? Get in the habit of checking whether the expected answer is one thing or several — that decides cuál versus cuáles, the same way any Spanish noun or adjective would need to agree in number.
Qué in exclamations — a completely different job
Qué has a second life entirely separate from asking questions: starting an exclamation. ¡Qué bonito! (How pretty!) ¡Qué calor hace hoy! (It’s so hot today!) ¡Qué de gente hay aquí! (What a lot of people are here!) Cuál never does this job — exclamations expressing “how [adjective]” or “what a lot of” always route through qué, not cuál, even when the underlying feeling is closer to picking out something remarkable from among many. It’s worth keeping these two functions of qué separate in your head: question word, and exclamation starter.
¿Qué tal? and other fixed greetings
Qué also anchors a handful of everyday greetings and small-talk phrases that are worth learning as fixed units rather than analyzing grammatically. ¿Qué tal? (How’s it going?) ¿Qué onda? (What’s up? — very common in Mexico) ¿Qué hay? (What’s new?) None of these ask for a definition or a selection in the way the core qué/cuál rule describes — they’re conversational formulas, and native speakers reach for them automatically without thinking about the underlying grammar, the same way an English speaker doesn’t parse “what’s up” literally.
Mistakes learners make
- Saying ¿Qué es tu nombre? instead of ¿Cuál es tu nombre? — asking for a name is a selection question in Spanish, not a definition question.
- Using cuál directly before a noun: ¿Cuál color prefieres? should be ¿Qué color prefieres? This usage does appear informally in some Latin American countries, but it’s considered nonstandard.
- Overcorrecting and avoiding qué near “es” altogether — ¿Qué es esto? is correct because it’s a genuine definition question, not a selection.
- Forgetting to pluralize cuál to cuáles when asking about multiple items: ¿Cuál son tus planes? should be ¿Cuáles son tus planes?
Frequently asked questions
What’s the difference between qué and cuál?
Qué asks for a definition or comes directly before a noun. Cuál asks someone to pick from options and typically comes before “es” or “son.”
Why is it “cuál es tu nombre” and not “qué es tu nombre”?
Because asking for a name is treated as selecting the right answer from many possible names, which is cuál’s job, not a request for a definition.
Do you use qué or cuál before a noun?
Qué, always: ¿Qué país visitaste? (What country did you visit?)
Is “cuál” ever used before a noun?
It happens in some regions, especially parts of Latin America, but it’s considered nonstandard in most formal Spanish. Qué before a noun is the safer, universally correct choice.
When do you use “cuáles” instead of “cuál”?
When the expected answer could involve more than one item: ¿Cuáles son tus hobbies? (What are your hobbies?) asks for potentially several answers, so it takes the plural form.
Do qué and cuál ever mean the same thing?
In some contexts they overlap loosely in English translation, but grammatically they’re not interchangeable — the noun-before-it and choice-among-options tests almost always point to a single correct answer.
