Likely a modern variant of Khadija or Kaia
Kiaja is a contemporary American name with ambiguous roots. It is often used as a creative phonetic variant of the Arabic Khadija, meaning 'premature child,' or as an elaboration of the Scandinavian Kaia, meaning 'pure.' Its usage is rare, appealing to parents seeking a unique, rhythmic sound.
