Tbh, imo, "-is" and "-ez" are far too similar sounding to really support different sets of inflections over a longer period. What you could have though is the nominative ending's grade of voicing influencing case inflections, so, idk, have a nominative in "-ez" turn the genitive (?) ending "-x" into "-g" or "-r" or whatever we would agree upon as a voiced equivalent to "x" (since the obvious option "ɣ" doesn't exist here).

Phonological inventory looks fine to me, don't you think though that all three of /b v w/ might be a bit much? Very few languages other than English have all three, and if our language is spoken, I'd assume most dialects would simplify to two or even just one forms ( just /β/ and /w/ for example).

Secondly, for the romanisation, why not take "x" for the sh-sound and "c" (or "ch") for the ch-sound? X for sh is common in many natural languages (Catalan, some South American Indian languages...), while I have never seen c for sh, tbh.

Stuff still going on here, people?

Maybe some kind of noun classes that aren't tied to gender?

i've started a dictionary in google sheets (i'm assuming this is a publicly viewable forum, so pm your email for edit access)

keeping it solely to content words and not functional words for now

Sorry for double-posting, but this is really a separate thought.

I don't want to exactly replicate English's case system, but I'd accept it with a little tweaking.  Like maybe throw in a fourth case, say, instrumental, to unite constructions like "in Terris" tarnuunan, "by road", "with jam" sogooan, "smiled upon by the stars" hodjeron (note metaphor), etc.

Pet peeve: My feet always being cold

they might be a bit heavy on the consonants.

I meant, base-10, base-12, base-14? Also, how irregular should the number words be? E.g. Mandarin has very regular numbers--11 is ten-one, 17 is ten-seven, 34 is three-ten-four, etc. English is less regular, and French is even less regular than English.

Random ideas for cardinal numbers:

1. aym
2. wal
3. con
4. vlare
5. gol
6. fwocp
7. yav
8. meqod
9. mirj
10. oj

What kind of number system do we want?

I don't think that's a good idea. I would support stuff like wide and down in English though.

ah! also we should allow w/y + any consonant in the coda
