Actually, no matter how you spell it it looks like EYE-a to me. Hmm. Aeha looks the most like AY-a to me, but it also looks really contrived and weird. Aaya or Aaia maybe-- I know a couple of people who have used "aa" as a long A sound (a
Jaala and an Alaajah). I think I like Aaia the best-- Aia and Aea are cool too, just because they are palindromes AND have no consonants!
