One of the most fascinating aspects of Spanish for English speakers is the use of double negatives. In English, saying "I don't know nothing" is considered grammatically incorrect. However, in Spanish, using multiple negatives in a sentence is not only correct but often necessary!

Why Do Double Negatives Exist in Spanish?

Spanish follows a concept called negative concord, meaning all parts of a negative sentence must agree. This differs from English, which follows the mathematical rule that two negatives cancel out to make a positive.

For example, consider this sentence:

No sé nada. (I don’t know anything.)

Here, both no (no/not) and nada (nothing) are used, yet the sentence still means “I don’t know anything” rather than "I know something."

Common Spanish Double Negatives

• No veo a nadie. (I don’t see anyone.)
• No tengo nada. (I don’t have anything.)
• No me gusta tampoco. (I don’t like it either.)

Exceptions and When Not to Use Double Negatives

Although negative concord is the rule, there are cases where using two negatives does change the meaning. If you place the negative word before the verb, you don’t need “no” at all:

Nunca voy al gimnasio. (I never go to the gym.)

Since "nunca" (never) is already before the verb, adding “no” would make it incorrect.
