The sound is nice, but I hate the spelling. I understand it makes it etymologically distinct, but I prefer
Kaya,
Kaia, And
Kaja by far.
The C makes it seems kind of fruity to me? Maybe my brain is just visually rearranging açai.
It sounds good beside nature names. Caia
Wren, Caia
Daphne, and Caia
Willow are stunning.
