Umm...really?
Looking over the letters you wrote, it took me some time to see that those were the letters in
Elijah (
Eliyahu) but backwards and missing the vav at the end. And I didn't know every letter has a separate meaning. Names are made out of words, and they're el (God) and Yah (half of God's name, I don't write it). So it means that [God's name] is God. And Hyla is just Eliyah(u) backwards. If Hyla actually did come from
Eliyahu, and not something else.
