Gothmog: the poll

[Boromir88]

I think it could be a toss-up between Nazgul or some sort of man (Black Numenorean).

As stated in one of those Gothmog threads I started I basically ruled out that he was an orc. I just don't imagine Sauron trusting an Orc enough to be second in command to his entire army. Though since Tolkien did never say the possibility is still there, but to me I'm 99 percent sure Gothmog wasn't an orc. Simply for the reason that I don't see Sauron giving an Orc that hight up in position. What would you argue, 3rd in command (Witch-king, Mouth of Sauron, Gothmog)?

It's reasonable to suspect he's another Nazgul. I mean if the Witch-King is first in command another nazgul could be second in command (would make sense). Problem is I thought Tolkien only came out and said he named two nazgul and he didn't feel it necessary to name them all (but I could be wrong).

My guess has always been Black Numenorean. Gothmog does not sound like a "man" name, however is it possible that his name was forgotten and was later named Gothmog? Sort of like how the Mouth of Sauron's name was forgotten.
