Coordinate vs position

Question

struct Point2D
{
  int x;
  int y;
};

There is a 2D tile-based map. How to name variable of type Point2D which represents coordinates of specific tile?

Point2D tilePosition;

or

Point2D tileCoordinate;

I have problem in understanding difference between coordinate and position.

Answer 1

Coordinate system is just a way to identify position, I prefer tilePosition. IMHO, naming is supposed to indicate the meaning of the variable, not what the inside structure is.
