"Īlvom kēlȳmi ozmijīli."

Translation: We will miss our cat.

[Joel__W]

Should it not be īlvon? Since it comes before /k/?

[Dedalvs]

Good question! Not at this stage, no.

[Joel__W]

Is it correct to assume that the prepositive comitative form of adjectives is invariable and always ends in -m then?

[Dedalvs]

Unless it ends with s.

[Ctxkh1Me]

Shouldn't the translation here for Īlvom kēlȳmi be "our cat?" The Comitative tips lists

NOUNS ENDING IN -I
NOM: kēli "cat"
GEN: kēlio "of the cat"
INS: kēlȳmi "with the cat"

It would be kēlȳmmi to be plural.

[Dedalvs]

It should, yes! Thank you for the correction. I'll fix it now!
