"Sit, my daughter."

Translation: Dēmās, ñuhus talus.

[Koen486171]

Is voc. sing. lunar here always ñuhus? Or would it become, e.g. ñuhis keelis (my cat! ) ? Because I tried ñuhas (default add -s) and it was wrong

[Xenon-]

Adjectives have 1 form for each gender/2 genders. So voc. sing. lun. for ñuha would always be ñuhus; it follows the declension of vala, voc. valus- voc. ñuhus. When you would call your cat, it would be: "Ñuhus kēlys!" (kēlius is reduced to kēlys via contraction).
