I adore
Sibylla and love
Sibyl. I can't abide the "
Sybil" spelling because I majored in Ancient Greek, and my rigid brain refuses to recognize "
Sybil" as a possibility because the Greek letters that are transliterated as "y" and "i" are distinct. (That's annoying, I know, but I can't help it LOL)
