What Dennis means

Dennis means a follower of Dionysus. The name identifies someone as belonging to the god rather than describing any quality of the person, which is how most theophoric names of its period worked.

Where Dennis comes from

Dennis comes through the French Denis from the Latin Dionysius, meaning of Dionysus — the Greek god of wine, theater and ecstatic release. That a name honoring a pagan deity became thoroughly Christian is down to Saint Denis, the third-century first bishop of Paris, who was beheaded on Montmartre and is said in legend to have picked up his own head and walked several miles while preaching. He is the patron saint of France, and the basilica of Saint-Denis holds the tombs of nearly every French king. The English Dennis is the Norman form; the same source gives Denise, Dion and the surname Dennison.
