EntityManager Query Question

I am learing JPA queries...

In a query like this....

Query q = em.createQuery("Select p from Person p where p.personName = John");

What is p ?

is p a place holder for a column name?

Why is it says Person p - I am confused with that

so when you say (using above example) p.personName I belive p referes to an object (or an entity). If so personName is the property defined in the Person class. Is that correct?
