Likely a modern variant of Mariah or Carina
Cariah is a rare contemporary name likely created as a blend of the prefix 'Ca-' with the established name Mariah, or as a phonetic variant of the Greek name Carina. Because of its rarity, it lacks a singular historical etymology and is often chosen for its melodic, lyrical sound. It shares the 'iah' ending common in Hebrew names, though it is not found in traditional religious texts.
