величие is a ness word already,ство for male and ность for female IIRC,don't take it for granted though ,I always just mix my polish and russian knowledge )))))
аий is your attempt to make I? I don't know such word and i'm sure it'd jsut be ай.without the additional I,unless i'm mistaken and there is such a word,in which case you wouldn't change it for я.
Russian is by far the hardest language I have tried learning so far... Especially all those grammar rules fuck with my mind Like Personal Pronouns I know quite well(I think), but Possesive Pronouns are a bitch in my opinion And Verb conjugtations are hard, but I am starting to see a pattern
I can't say i know half thoose grammar related words you've stated,but i'll have you know that Slavic languages in general are pretty tough to learn for non Slavic speakers ))))))
What I wanted to say was:
Dont take his dog, the dog is from him.
Kind of like:
1: Is that your dog?
2: No, the dog is from my mother.
