Cindy f
English: pet form of CYNTHIA (SEE Cynthia) or, less often, of LUCINDA (SEE Lucinda), now very commonly used as an independent given name, especially in America. It has occasionally also been taken as a short form of the name of the fairy-tale Cinderella, which in fact is not related to it (French Cendrillon, a derivative of cendre cinders).
