Cyndi

Cyndi is an English given name that arose as an informal spelling variant of Cindy, itself a diminutive of Cynthia. Cynthia derives from the ancient Greek Kynthia, an epithet of the goddess Artemis meaning of Mount Cynthus, referring to her legendary birthplace on the island of Delos. The spelling with a y reflects a mid-twentieth-century American trend of playful orthographic variation in feminine names. Related forms include Cindy, Cynthia, and Sindy.
