Possibly a modern variation of Cynthia, meaning moon goddess
Cyniah is a contemporary American name likely created as a creative variation of the Greek name Cynthia. Cynthia refers to the goddess Artemis, who was born on Mount Cynthus, and is deeply associated with the moon. The addition of the '-iah' suffix gives it a rhythmic, melodic quality similar to names like Aaliyah or Kehlani.
