The letter 'C' or the sound it makes, or a shape that resembles the curved letter C.
Spelled-out version of the letter C, using English phonetic spelling. The letter C itself comes from Latin, Greek, and Phoenician origins, evolving from a character representing a camel's head.
The letter C is alphabetically useless—it's never needed since K handles the hard 'c' sound and S handles the soft one. English got stuck with it because it inherited C from Latin, where it was essential. French complicated it further, making C soft before E and I but hard otherwise, a rule English mostly adopted, creating the spelling chaos we see in 'city' versus 'catch.'
