Dennis

Dennis is an English given name derived from the Latin Dionysius, itself from the Greek Dionysios, meaning "of Dionysus," the Greek god of wine and festivity whose name may ultimately relate to Zeus combined with a pre-Greek element of uncertain origin. The name was borne by Saint Denis, the third-century martyr who became the patron saint of France, which helped spread the name throughout medieval Europe. Denis is the standard French form, while Denys appears in Ukrainian and other Slavic traditions, and Dionisio remains common in Spanish and Italian contexts.
