Now that we have some substantial pronunciation, let's get started on vocabulary!
Here's some of the ideas from earlier, in both consonant root form and the other form that they were in before.
Word - ber-/B-R-S
Earth - terr-/T-R-N
Language - Terris (?)
Father - pas-/P-S-M
Mother - mer-/M-R-M or M-S-M
Son - id-/-D-H
Daughter - id-a/-D-AH
Food - su-/S-D-L
proposal:
earth - tarn
of earth / like earth / belonging to earth (?) - tarnuu
our language (nominalised form of that last one) - tarnuun
How would a double u be pronounced?
Another idea have a suffix for opposites? This would cut the number of words substantially. Hot & Cold. Young & Old. etc
I don't know if it's a good idea, but it could simplify things and make it easier to learn the language more quickly.
Or a prefix nonhot=cold nonold=young or unhot instead of nonhot etc etc
Then there would be halfhot for lukewarm. Maybe zerohot for cold? zero-old or little-old for young.
Has this been tried in any Conlangs before?
If you are speaking another language to someone who doesn't at the same time speak English, you can't say "How do you say 'cold'"? Because that person wouldn't know the meaning of "cold". But, if you remember the word for hot, you could say "what is the opposite of hot?".
My point is, that maybe the idea of simplifying the language with adding an "opposite of" suffix may be unnecessary and therefore a bad idea.
I have a tendency, perhaps an irritating one, of "thinking out loud".
As evergreen said, I like this as a thing to add variance, but not as a standard practice.
