Using 'very' with a noun

Are these correct ways to use very with a noun?

She is the very girl I want.

On the very year of 2012, comes the end of the world.

This is the very company everyone wants to work for.

What I understand is that very can be used to emphasize the importance of a noun.


It is correct, and the dictionary gives a definition for "very" used this way:

precise; particular: That is the very item we want

so, "very" can be used to indicate that something is the right and exact thing you were looking for.
