Crescent

For things named Crescent, see Crescent (disambiguation).

The English Wiktionary has a dictionary definition (meanings of a word) for: crescent

An example of an artistic crescent — in this case a large circle with a smaller one removed.

An astronomically correct crescent shape (in blue), complemented by a gibbous shape.

In art and symbolism, a crescent is generally 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).
