Denny is associated with the meaning “Follower of Dionysus, god of wine” — a beautiful sentiment to see brought to life in your child’s room.
Denny is a shortened form of Dennis, which comes from the Greek name Dionysios. That name belonged to Dionysus, the Greek god of wine and celebration. The Latin version, Dionysius, was widely used in the early Christian church. So at its core, Denny carries the meaning "follower of Dionysus" or "devoted to Dionysius."
