Language and rank name Warder

[Gnoth]

Thats fine? I don't see how that is silly, Goth in orcish and Goth in english mean two different things. Orcs take words and debase them and twist them to fit their own uses. Your first post detailing how you dislike and think its our use of mixed blackspeech/english is really unfounded in rp lore too. Blackspeech was only spoken in full by high ranking people in Sauron's camp, most would just use it brokenly. This wikipedia excerpt details it better than I:

The Orcs had no language of their own, merely a pidgin of many various languages. However, individual tribes developed dialects that differed so widely that Westron, often with a crude accent, was used as a common language. A few words of the Black Speech are common among Orcs: ghâsh ("fire"), sharkû ("old man", leading to Saruman's nickname "Sharkey"), snaga ("slave"), and Uruk ("orc"). Another Orkish word is tark ("Man of Gondor") from Westron and ultimately Quenya tarkil.

When Sauron returned to power in Mordor in the Third Age, Black Speech was used by the captains of his armies and by his servants in Barad-dûr.

So my biggest gripe with your suggestions of Chief or Boss is that these are more widely used in everyday english than Warder, and are extremely generic sounding and invoke images of Native Americans/Police/Mobsters and other things.
