One request from the session today was to come up with an Orkish/Black Speech name for Morgoth. What do the denizens of Angband call him? Obviously they can't call him Morgoth - that's Fëanor's name for him. And 'Bauglir' means 'tyrant', so while accurate, probably not his preferred name. But Melkor doesn't really fit now, either.
There could be some hints in Sauron's Morgoth-cult on Numenor. One of the things the high priest Sauron has the Numenoreans call Morgoth is 'the Lord of All'. It sounds like the kind of title Melkor would appreciate - it's a little blasphemous and challenges Manwë's rule. 'Lord of Arda' or 'the Dark Lord' could also work.
Obviously, we know only a very little Black Speech, and it was invented by Sauron well after the First Age. But. His Black Speech was based on Melkor's attempt to give the orcs a common language ('Orkish'), and was ultimately based on his own native tongue (Valarin). And very luckily, here is part of the corpus for the Black Speech:
Lugbúrz = the Dark Tower
and
durbatulûk = 'to rule them all'
So, we have búrz = dark
and durb-at-ul-ûk = rule-(infinitive)-them-[completely]
You can turn an adjective into a noun with
-um (burzum = darkness), but I don't know how to make the verb 'rule' into the noun 'ruler'
It would be nice to be able to say either 'the Dark Lord' or 'the Lord of All' in the Black Speech, but as far as I know, Tolkien did not tell us that.
I don't suppose anyone here knows anything about the Hittite language? It is a non-IndoEuropean language that has some commonalities with the Black Speech (according to Alexandre Nemirovsky), so Hurrian-Urartian would probably be as good a place as any to look for parallels. We can always claim it's Morgoth's version (distinct from Sauron's version) anyway.
[Oh...and obviously, I looked all of this up on Ardalambion;

EDIT: Well, thanks to the internet, I found an Hurrian-Uratian glossary, which was apparently all the rage back in the 1940s. I have to agree that these words look like they would fit right in with Black Speech. There is totally a tribe of orcs somewhere whose dialect is (essentially) Hittite.
arš-u-, rule
(LÚ)ere/i-li, king
eur-i, lord, ruler
ibir-ani, whole, complete, full
nul-du-, overpower, rule

It is cool what you can learn about what matters to people, in what bits of their language got preserved. They cared about whether or not land had water on it. Guess they lived somewhere arid....
But anyway, their word for lord/ruler was
euri, so I figure we incorporate that into what we already have. (And do you leave off the -i in nominative case? I don't even know how to read this glossary....)
So, Durbibúrz or something would be Dark Lord, right? Sounds pretty dumb.
*sigh* I feel like there are enough pieces here to do something cool that still sounds harsh and unlovely. Ah well.
