"Bisi kirini ābri issi."

[KPatrickWV]

How would you make this a copula? "these women are happy" ?

[mlamm]

I imagine it would be as simple as switching the order of the noun and adjective.

So would it be "Bisi ābri kirini issi."?

[AnabellPerezr]

Why use the "kirini" and not the "kirine"?

[OliverBens6]

Adjectives, nouns, verbs, and possessives all conjugate depending on the gender, number, and case of the noun. In this sentence, women is plural, so "kirine" becomes its' plural form "Kirini". This also happens with "Syz" becoming "Syri". It's just changing from singular to plural, like how in English you have: I run - She runs. Just how it conjugates. Have a look at these tables for more help:

Syz: https://wiki.dothraki.org/High_Valyrian_Adjectives#S.C8.B3z-type

Like I said, this happens with all adjectives, nouns, verbs etc. I had to redo the course on this account, and I write all the translations in my notebook to help me understand. I hope that helps.
