Today, every Dennis, Denis and Dionysius you know shares a name day with the Greek community. In many Greek families the everyday form is Dionysis, from the formal Dionysios, but the name has travelled widely enough that a classmate named Dennis, a co-worker named Denis, or a neighbour with the older form Dionysius can all be folded into the same warm wish.
The name goes back to Greek Dionysios, meaning “of Dionysos” or “belonging to Dionysos,” formed from the name of the ancient Greek god Dionysos with the adjectival ending -ios. Through Greek and then Latin Dionysius, the name spread across Europe and gradually produced shorter vernacular forms such as French Denis and English Dennis. It is one of those names whose Greek origin is unmistakable, even when it arrives in a very familiar Canadian form.
In Eastern Orthodox Christianity, a person’s name day is the feast day of the saint after whom they were named at baptism.
That gives today a nice wide circle. It belongs to the papou Dionysis who still signs cards with his full formal name, to the cousin Dennis everyone knows from hockey or university, and to the colleague Denis whose name may have come through French rather than Greek but lands on the same date all the same. There is something vivid and theatrical in the name’s long history, and it suits the friend who fills a room with stories just as easily as the quiet uncle who becomes the centre of the table once the coffee is poured.
Chronia Polla! to everyone celebrating today, in Greek and non-Greek circles alike. If you know a Dennis, Denis or Dionysius, today is a perfect day to send a quick “happy name day,” explain the tradition, and let a small piece of Greek culture brighten someone else’s afternoon.
