1. We use no ( = ‘not a’, ‘not any’) immediately before a noun.
- No aeroplane is 100% safe.
- There’s no time to talk about it now
Before another determiner (for example the, my, this), we use none of.
We also use none of before a pronoun.
none of + determiner + noun
none of + pronoun
- None of the keys would open the door.
- None of my brothers remembered my birthday.
- None of us speaks French.
When we use none of with a plural noun, the verb can be singular (more formal) or plural (more informal)
- None of my friends is/are interested
2. We can use none alone without a noun.
- How many of the books have you read. None.
3. When we talking about two people or things, we use neither, not none
- Neither of my parents could be there. (NOT none of….)
