Well, this may seem a bit general but, does anyone know the language conventions, grammar, verb/noun endings for either of these two languages. I have trawled the internet (but im bad at trawling), and UESP isn't that helpful...
...so basically, any good, practical information about writing/translating either of these two language, any help appreciated

Well there isn't so very much about it but UESP have some decent articles about it if I dont remember incorrectly.

And TIL might have some interesting stuff as well.

whats that?

TIL = The Imperial Library a great site for Lore.

http://imperial-library.info/

that kinda weird,ive been to that site a million times and i did'nt know it was til for short :facepalm:

Then you have learned something new today.

There is no Dwemer language. We do have some Dwemer glyphs but they are the same as used by the Ayleid glyphs and should probebly be called Elven Glyphs.

The UESP has made an extensive list of translated Ayleid words though.

Considering you've already been there, I reckon you've seen all there is.
