Origin: Irish

Meaning: Watchful, vigilant; pure

Casen is a gender-neutral name of Irish and English origin, meaning "vigilant," "watchful," or "pure." In Irish, Casen is a variation of Casey derived from the Gaelic word cathasaigh, meaning "vigilant" or "watchful"- a befitting choice for a particularly observant little one. In English, however, Casen means pure and is thought to be a nickname from Catherine, which shares the same meaning. A derivative of many names, Casen offers a fresh take on the classics, making it a stylish choice for a modern-day baby.
