Copy this definition of texture
Texture: The way the surface of an object feels to the touch.
This is called actual texture. Actual texture may be rough, smooth, grainy, slick, gritty, etc.
Artists also create simulated texture. You can see these textures and imagine how they would feel, but if you touch them they only feel like the surface on which they've been drawn, painted, or printed.
