Grammar rule

One negative is enough

One negative in a sentence

In standard English, a sentence (or each part of a sentence) has only one negative word: not, never, nobody, nothing…

not + an any- word	or a no- word
I didn't see anybody.	I saw nobody.
She didn't say anything.	She said nothing.
We didn't go anywhere.	We went nowhere.
There wasn't any milk.	There was no milk.

anybody = anyone · nobody = no one (two words). In conversation, not + an any- word is more usual: I didn't see anybody.

Not I didn't see nobody and not She didn't say nothing: that is two negatives.

At the start of a sentence, use a no- word

Nobody called. Nothing happened. (not Anybody didn't call)

never

never is negative too, so it goes with an any- word: I never eat anything after nine. (not I never eat nothing)

In songs and in some kinds of English, you can hear two negatives: "I can't get no satisfaction." In standard English, use one.
