Denny

Denny is an English given name that originated as a medieval diminutive of Dennis, itself derived from the Latin Dionysius and ultimately from the Greek Dionysios, meaning "of Dionysos," the god of wine and festivity. The name has been in steady informal use in English-speaking countries, functioning both as a nickname and as an independent given name. Dennis and Denis are the principal full forms from which Denny descends.
