What is the difference between brick veneer and brick masonry?

Masonry implies bricks, blocks, or stones held together with mortar. Bricks are fired ceramic. Blocks are usually formed concrete. And stones are formed naturally and quarried from the earth. They are held together with mortar. Concrete is used as mortar, but concrete can also be poured to make slabs and foundations. I think the difference is that concrete can be used by itself without being considered masonry. For example, even statues can be made from concrete by pouring them into a mold.
