Basic Negation with No

The most common way to make a sentence negative in Spanish is to place the word no directly before the conjugated verb. Unlike English, Spanish does not need auxiliary verbs like do or does to form negatives. This simplicity is one of the first things learners notice, but the placement of no relative to pronouns requires a little care.

Quick comparison with English

Notice how Spanish needs one extra word (no), while English requires reshuffling the verb with do/does/did. This is one of the few areas where Spanish grammar is genuinely simpler.

Placing No Before the Verb

In a basic sentence, no goes immediately before the verb. Nothing else comes between them except object pronouns (which we'll see below). The position is fixed and predictable, which makes negation one of the easiest things to learn at the beginner level.

Notice that there is no equivalent of English do/does/did. You simply take the affirmative sentence and add no in front of the verb.

No auxiliary needed

English relies heavily on do-support for negation: I don't know, he doesn't like it, they didn't arrive. Spanish has no such requirement. The negation word attaches to the main verb itself, with no helper words at all.

Compare this with how English speakers often stumble when translating literally. You never say "No hago saber" for "I don't know"; you just say No sé.

Position with object pronouns

When a verb has one or more object pronouns (me, te, lo, la, le, nos, los, las, les, se), the no goes before the pronouns, not between them and the verb. The entire pronoun-verb unit stays together as a single block.

This is one of the most common mistakes beginners make. Do not say "Lo no sé"; the no must come first.

Negating Compound Tenses

For tenses formed with haber (perfect tenses) or estar (progressive), the no still goes before the auxiliary verb, which is treated as the main verb for placement purposes.

Again, object pronouns that attach before the conjugated auxiliary still fall after no:

Negating Infinitives

When you negate an infinitive (the -ar/-er/-ir form), no sits directly before it. This often appears after expressions like prefiero, quiero, es mejor, or in instructions.

Short Answers and Emphasis

No can also stand alone as a short answer, just like in English. When used this way, it is often followed by a full negative sentence for clarity or emphasis. You will learn more about this pattern in Responding Negatively to Questions.

A Word About Stress

Spoken Spanish gives no a clear stress when it carries emphasis: "No, NO quiero ir." The first no is the answer; the second one carries extra weight to make the rejection emphatic. Without that prosodic stress, repeated no simply sounds like a normal "no, I don't…" answer.

Once you're comfortable with basic no, the next step is learning the other negative words in Spanish, such as nada, nadie, and nunca. See Negative Words for a full list, Double Negation for sentences with multiple negatives, and Responding for short-answer patterns.
