Cassie

Cassie is a familiar form of Cassandra and can also be used as a complete given name. Cassandra’s association with prophecy comes from Greek mythology, but “prophetess” describes the mythological figure’s role rather than a certain literal translation of the name. Cassie carries that name-family connection without requiring the full form in everyday use.

The short form keeps Cassandra’s opening sound and gives it an ee ending. Choosing Cassandra leaves several possible everyday forms, whereas choosing Cassie directly makes the preferred short name official. Because Cassie can be used informally for more than one longer name, a family namesake’s own full name remains the best guide to the particular history intended.
