35. How Negatives Work

Source: A Complete Guide To Every Fundamental In Spanish (The Conclusion)

Spanish negation centers on the word no placed before the verb. Unlike English, Spanish freely allows — and often requires — double or triple negatives. When a negative word (nada, nadie, nunca, ningún, tampoco) comes after the verb, no must precede the verb.

Key Rules

Place no directly before the conjugated verb: Yo no hablo francés.
Double-negative rule: if a negative word (nada, nadie, nunca, ningún, tampoco, ni…ni) follows the verb, you must keep no in front of the verb.
A negative word placed before the verb does not need no: Nadie come = No come nadie.
Use the personal a with alguien and nadie when they are direct objects: ¿Viste a alguien? / No vi a nadie.
Algún / ningún drop the -o before a singular masculine noun (algún libro), but show full forms otherwise (alguno, alguna, algunos, algunas; ninguno, ninguna).
Ninguno/a is rarely used in the plural in modern Spanish (singular is standard).

Nadie come.	Nobody eats.
Ella nunca corre.	She never runs.
Yo no como nada.	I don't eat anything. (lit. I don't eat nothing.)
Yo no veo nada.	I don't see anything.
Tú nunca comes nada.	You never eat anything.
Él no sabe nada.	He doesn't know anything.
¿Viste a alguien? — No, no vi a nadie.	Did you see anyone? — No, I didn't see anyone.
¿Tienes algún libro aquí? — No, no tengo ningún libro aquí.	Do you have any book here? — No, I don't have any book here.
¿Conoces alguna tienda por aquí? — No, no conozco ninguna.	Do you know any store around here? — No, I don't know any.
Yo tampoco.	Me neither.
No quiero ni café ni té.	I want neither coffee nor tea.

Notes & Gotchas

Spanish double negatives are mandatory, not optional, when a negative word follows the verb.
Triple negatives are perfectly valid: No vi a nadie nunca.
Use jamás for emphatic "never" — even stronger than nunca.
Ningunos / ningunas exists but is uncommon; native speakers prefer the singular: No tengo ningún libro rather than ningunos libros.
Alguien / nadie are invariable (no gender, no number).
