Pure or chase
Chassie is primarily considered a diminutive form of Chastity, derived from the Latin word 'castus' meaning pure. It may also function as a rare nickname for the occupational name Chase, or as a modern phonetic variation of names like Cassie. It has a vintage, nickname-style quality that was more common in the late 19th century.
