What does the name Casie mean?
Casie is a spelling of Cassie, pronounced the same way, so it shares Cassie's meaning and origin.
Cassie is a pet form of Cassandra (and sometimes of Cassidy), made with the ending -ie. Cassandra is the Trojan princess of Greek legend who could foretell the future but was never believed. DMNES calls the Greek name of uncertain origin: one part may come from the word for "man", and scholars have proposed other roots meaning "excel" or "raise". Cassie was most popular in the US in the 1980s.
