Near as a preposition
Near can be used with or without to. To is not normally used when we are talking about physical closeness.
When we are not talking about physical closeness, near to is often preferred.
- I came very near to hitting him. (NOT I came very near hitting him.)
Nearer and nearest are generally used with to, though to can be dropped in an informal style.
- Come and sit nearer to me.
- Who is the girl sitting nearest to the door?
