What is the name of the marking that refers specifically to a patch of white that can occasionally occur without a star?

The marking that refers specifically to a patch of white on a horse that can occur without a star is known as a snip. A snip is defined as a small white marking usually found on the horse's muzzle, specifically between or adjacent to the nostrils. This term is used to describe this type of marking distinctly, as it does not overlap with other facial markings like a star, which is a small white patch on the forehead, or a blaze, which runs down the horse's face. Understanding these definitions is key in horse evaluation, as they help in identifying and describing horses accurately based on their physical characteristics.
