Crescent
（重定向自Increscent）
In art and symbolism, a crescent (US: /ˈkrɛsənt/, UK: /ˈkrɛzənt/) is the shape produced when a circular disk has a segment of another circle removed from its edge, so that what remains is a shape enclosed by two circular arcs of different diameters which intersect at two points (usually in such a manner that the enclosed shape does not include the center of the original circle).
