History & Origin

Cassy is the short form of Cassandra, the ill-fated Greek prophetess, or of Cassidy; either way it inherits the parent's meaning. Like many mid-century nicknames it was written straight onto birth certificates, peaking in 1986. A girl named Cassy then is now in her late thirties.

The spelling is the low-key member of a Cassie/Kassie/Cassi family, and it reads more retro-informal than reviving. Parents who like it tend to also consider Cassie, Cassandra, and Cassidy.

Did you know? Cassy is the plainer cousin of Cassie and Kassie, a short form parents began giving outright, cresting in 1986.
