Nazgnagol (From Rings Of Power Season 3)

Maybe could be

Black Speech: Naz --> Ring

Nagol = Quenya --> Tooth

As Parmandil put it on Discord: "It feels more like a parody name than a serious Conlang attempt. Esp since the Nazgûl prob wouldn’t be known as a group before they wrathified".

Which I agree with 100%.

I doubt it means' like they state Ring-servent, if anything they should have used the attested BS. snaga n. “slave”. But oh, well. It is what it is.

Given that Ostetter and Leith McPherson are collaborating—and have collaborated—on the series, I doubt it is "a parody game."
