Here are some ways "none" is used:
* To refer to a lack of quantity: "There are none left."
* To refer to a lack of individuals: "None of the students were present."
* To refer to a lack of specific things: "None of the answers were correct."
* To refer to a lack of quality or characteristic: "The room was completely bare, none of the furniture was left."
Examples:
* "I have none of your money." (I don't have any of your money.)
* "None of the guests came to the party." (No guests came to the party.)
* "None of the questions were answered correctly." (No questions were answered correctly.)
It's important to note that "none" can be singular or plural depending on the context. If it refers to a single item or a group of things considered as a whole, it is singular. If it refers to multiple individuals or things considered separately, it is plural.
For example:
* "None of the cake is left." (Singular - referring to the cake as a whole)
* "None of the students were late." (Plural - referring to individual students)
