Negative Pro-forms 

The English no-series words and some other words are considered inherently negative (also called inherent negative universal), which means they can make a sentence negative on their own.

Negative words are inherently negative, that is why they do not need another negative maker in a sentence. We use 'no one', 'nobody', 'nothing', and 'nowhere' with an affirmative singular verb. For example:

Since the negative pro-forms are inherently negative, they negate the whole sentence and using another negative marker in the same sentence would form a double negative which is grammatically unacceptable.

Negative pro-forms are not used in questions. Instead non assertive pro-forms are used to form interrogatives.

When negative-pro-forms are used in a sentence, the verb remains positive, but the overall meaning of the clause becomes negative. So, the question tag must be positive.

Negative pro-forms are considered singular and accordingly take singular verbs.
'Neither" can be used as a pronoun or a determiner to refer to two people or things. In both cases it is followed by a singular verb. When it is used as a determiner, the following noun must also be singular.

'No' and 'None of' are also negative determiners, but the difference between them is that 'no' is followed by a singular noun and singular verb while 'none of takes a plural noun or pronoun and a singular verb.

In informal English, a plural verb might be used after 'none of'.
