Giving brainliest
is "you" first person, second person or third person?
give an example

It depends but "you" is second person. An example is when an author is telling a story in first person saying "I messed up" and he continues by saying "now you may be wondering how I did this".

That is second person.

Here is the rule of person:

First person: I / Me / My

Second person: You

Third person: He/she / They

In short, Your Answer would be: 2nd person

Hope this helps!
