Meaning & origin
Cassidie is a feminine given name that emerged in the United States in the early 1980s as a respelling of the surname Cassidy. Its use peaked in 1998, when it was given to 46 baby girls, before entering a steady decline through the 2000s and 2010s. While Cassidy itself has been a popular unisex choice, the Cassidie spelling is overwhelmingly feminine and has never cracked the top 1000 names. The name's trajectory reflects the broader trend of creative respellings that flourished in the 1990s but have since fallen out of favor. Unlike the more common Cassidy, Cassidie has seen no significant revival in recent years.
Cassidie is a respelling of Cassidy, which derives from the Irish Gaelic surname Ó Caiside, meaning 'descendant of Caiside'. The personal name Caiside is thought to mean 'curly-haired'. Cassidy has been used as a given name primarily in the United States since the mid-20th century, and Cassidie is one of its many modern respellings.
