I know the Dunmer use a lot of Daedric alphabets in their writings. Dunno about their own language though.
Yep, there's a whole lot on dunmeri language, it's practically an existing language you could technically learn how to speak.
Id look for examples in Morrowind.
Tel means tower, Mora means forest. Tel Mora, Sadrith Mora, tower forest, old forest. Bal Molag Mer, Stone Fire Men, Balmora, Stone Forest.
You can just take your own nomenclature that denotes your island and make it unique as you go.

I know those, that's like basics of the basics.
Unfortunately, I haven't ran into any such words because there is none mentioned, or I missed it so there's nothing I can use as an example. I'd rather avoid making my own therm since fatter chance is that I missed it rather than it not being mentioned ever (considering Morrowind is practically surrounded by water) hence why I'm asking lore pros.
N'WAH!! FLETCHER ! lol those the only words i know
I beg your pardon, I'm a total f'lah!
Tbh, I still have no idea what fletcher means, aside from a person that fiddles with arrows. XD Maybe it's not dunmeri...
