When you're trying to figure out how to say what in Spanish, you'll quickly discover it doesn't have a single, universal translation. Depending on whether you're asking a question, expressing shock, or connecting clauses in a sentence, you'll reach for words like qué, cuál, cómo, or lo que. Grasping these distinctions early prevents awkward phrasing and helps you sound natural from your first conversation.
The most common translation for "what" in direct questions is qué, but you can't use it everywhere. If you're asking for a definition or general information—such as "What is that?" (¿Qué es eso?)—qué is correct. However, if you're asking "What is your phone number?", Spanish speakers use cuál (¿Cuál es tu número de teléfono?). Sorting out these nuances comes down to context, sentence structure, and understanding what you actually want to communicate.
The Core Translations: Qué vs. Cuál
Choosing between qué and cuál trips up almost every beginner. While English uses "what" for both scenarios, Spanish draws a firm line based on whether you're looking for an open-ended concept or selecting from a set of options.
When to Use Qué
You use qué (always with a written accent when used in questions or exclamations) as a pronoun or an adjective. As a pronoun, it's followed directly by a verb:
- ¿Qué quieres comer? (What do you want to eat?)
- No sé qué necesitas. (I don't know what you need.)
As an adjective, qué is followed immediately by a noun to specify which kind or what type of thing you mean:
- ¿Qué coche compraste? (What car did you buy?)
- ¿Qué libro estás leyendo? (What book are you reading?)
You also use qué in exclamations to express intensity:
- ¡Qué calor hace hoy! (It's so hot today! / What heat!)
When to Use Cuál
While dictionaries often translate cuál as "which", it frequently functions as "what" in Spanish when you aren't asking for a definition. Specifically, use cuál (and its plural form cuáles) when you're choosing among specific options, or when "what" is followed by the verb ser (to be).
- ¿Cuál es tu apellido? (What is your last name?)
- ¿Cuál prefieres, el rojo o el azul? (What do you prefer, the red one or the blue one?)
A reliable rule of thumb: if you can substitute "which" for "what" in English without changing the meaning, you almost always need cuál in Spanish. For official guidelines on grammar and accentuation rules, consult the Real Academia Española.
Expressing Disbelief: How to Use Cómo
Sometimes "what" isn't a question at all, but an interjection thrown out when you didn't catch something or when you're stunned by what someone just said.
In English, you might say "What?" or "Pardon?". In conversational Spanish, you can use ¿Cómo? for this exact purpose:
- Persona A: Mañana no hay clases. (There are no classes tomorrow.)
- Persona B: ¿Cómo? (What? / Come again?)
Using ¿Cómo? here is polite and extremely common. While you can also say ¿Qué?, doing so can occasionally sound blunt or aggressive depending on your tone of voice. Sticking to ¿Cómo? keeps your interactions smooth and friendly.
Connecting Thoughts: Using Lo Que
When "what" appears in the middle of a sentence—meaning "that which" or "the thing that"—you drop the question mark, drop the accent, and use lo que.
This construction ties clauses together seamlessly without asking a direct question:
- No entiendo lo que dices. (I don't understand what you are saying.)
- Haz lo que quieras. (Do what you want.)
- Lo que más me gusta es viajar. (What I like most is traveling.)
Notice how lo que acts as a neutral relative pronoun. You'll hear this structure constantly in native media and daily conversation. To supplement your listening practice with authentic Spanish content, you can explore resources provided by the Instituto Cervantes.
Common Mistakes to Avoid
Language learners often fall into predictable traps when trying to express "what" on the fly. Avoiding these pitfalls will elevate your fluency immediately.
- Forgetting the accent mark on questions: Writing que instead of qué in a question changes a vital grammatical marker. Always keep the accent on interrogative qué.
- Using cuál before nouns: Cuál cannot sit directly in front of a noun. You cannot say ¿Cuál libro?—you must say ¿Qué libro?
- Translating "What is your name?" literally as what: In Spanish, you don't ask what your name is; you ask how you call yourself (¿Cómo te llamas?).
Frequently Asked Questions
Can I use qué and cuál interchangeably?
No. While they overlap in a few edge cases, mixing them up changes grammatical correctness. Use qué for definitions and before nouns, and cuál with the verb ser or when choosing from a specific set.
Is saying ¿Qué? rude when I didn't hear someone?
It isn't strictly rude, but it can sound abrupt. Using ¿Cómo? or ¿Mande? (common in Mexico and parts of Latin America) is safer and sounds much more polite.
What is the difference between que and qué?
The version with an accent (qué) means "what" in questions and exclamations. The version without an accent (que) means "that" or "which" as a conjunction.
How do I say "What if..." in Spanish?
You can express "What if..." by using phrases like ¿Y si... ? or ¿Qué tal si... ?, followed by a verb in the past subjunctive or present indicative depending on the context.
