The topic is closed, so i've opened a new now. I found out what n'wah and others mean.
Sera means sire or sir, so muthsera must refer to my lord (my sire) ->sire in the meaning of king (old usage)
N'wah must be invader (to enter into and spoil), it is clear, only it is cut
Scum is an existing word, means an immoral person (just if someone doesn't know)
S'wit - i'm not sure if that is the right answer, but i guess s'wit must be connected to the word 'witless' (maybe in a change and unused form of diswit?), this one i really can't tell wtf is
Anyone has tips or any responses?

Quite an interesting dictionary of Morrowind words and slang, a lot of it most likely speculation, but it is an interesting read.

I am convinced S'wit is abbreviation of softwit (that is idiot).

Tamriel Rebuilt has a translator, I'll ask there.

Yeah, it must be softwit. Yet i'm no english or american, i don't know all the words, but that must be it. But i think these words have nothing to do with languages in the game, it's just a local slang there. My 'researches' based upon the grammar and word usage of this real word. I just thought of slang words, and they look exactly like that. For example, they say:
'this is the end of you, swit' - which means 'i'll kill you, stupid b*****'
N'wah is really sure means invaders. If you talk to a dreamer, he will say something about 'the n'wah must die' and gives a talk about clearing the enemy out of Morrowind. I'm sure these n'wah must be the imperials, who actually invaded Morrowind.
Thanks for the softwit, my dictionary doesn't have that word, now my knowledge is increased by 1 points, needed for level advancement: 52 points

I really hope they include slangs like this in Oblivon (or even more of them), it makes the game...better, I love those strange words from morrowind, it makes the game a bit more unique.

Just like in X2: The Threat, rather than having standard 24h time it has its own time system, called zuran time. It somehow enhances the game.

What does that have to do with this topic? Did you post in the wrong thread?

I -think- he was referring to when each game has little touches of its own culture or wording, it makes the playing experience unique. EG: the slang in Morrowind.
