Unknown; possibly a modern variant of Keona or Quiana
Kyonna is a modern American invention with no singular established etymology. It is likely a creative blend of the prefix 'Ky-' with the popular suffix '-onna', or a phonetic variant of Keona, which has Hawaiian roots meaning 'God's gracious gift'. Because it is a contemporary creation, its meaning is often attributed to the names it resembles.
