What Is the Difference?
'Anybody' refers to an individual in a group; it doesn’t matter which person.
'Everybody' refers to all the members in a group.
If the answer is yes, it means all of the people in the group want tea. If the answer is no, it means all don't want tea.
If the answer is yes, it means at least one person wants tea. If the answer is no, it means nobody wants tea.
'Anybody' means any possible people. In a context where we don't intend to find only one person and we want to address a group, we use 'anybody', for example:
'Anybody' is a pronoun that refers to no specific person.
'Everybody' refers to all the people in a group. It refers to every single individual in a group.
When Can We Use 'Anybody'?
'Anybody' is usually used:
- in negative statements;
- in affirmative statements with negative meaning;
- in questions;
- in conditional clauses;
- for emphasis.
This is one example of affirmative sentences that we cannot use 'anybody' in it.
This example is correct.
However, sometimes they can be used interchangeably.
