Eh. I don’t speak Hebrew, I’m not Jewish, and I’m no longer Christian, so I really don’t feel like arguing about the names of angels in Judeo-Christian mythology. I’d probably get my butt trounced by someone later in the thread anyway.
I will say, though, that the names Lucifer and Metatron, according to Wikipedia (for what that’s worth), both appear to originate from Latin, and the ones ending in -el seem to originate in Hebrew.
There are probably other angels whose names don’t end in -el, so again, I’m not going to argue, but the ones most familiar to me (Michael, Uriel, Gabriel, and Samael) all fit that pattern.
