The second person point of view is not as widely used as first or third person in terms of literature, but it is just as useful.
This point of view uses the words 'you', 'your', or 'yours'. It can address someone (typically a reader or listener) or a group of people by using plurals as well.
This point of view is often recognized in letters (the ones you might send a relative), or emails (maybe for work-related purposes). While we're on the topic of working, you may have noticed second person point of view when listening to or giving a presentation.
The possessive cases are 'your' or 'yours'. The subjective and objective cases are 'you'.
This particular point of view is used to directly address or 'talk to' an audience. It is not frequent in literature, but it is widely used at work and everyday things.
