grammar.negation.double-negation
Double negation is mandatory: no veo nada
A negative word after the verb requires no before it: no vino nadie, no como nunca carne. Fronting the negative drops the no: nadie vino.

Erklärung
Spanish negatives concord — they don't cancel: no le dije nada a nadie ('I didn't tell anyone anything') stacks three negatives naturally.
Two valid patterns, one meaning: no + verb + negative (no llamó nadie) or negative + verb (nadie llamó). What's impossible is a bare post-verbal negative: *vino nadie.
