I am trying to learn the grammar and adjectives. I am not sure that I got it all right so please correct me if I am wrong. I think that there is a distinction between if the noun "has a heart beat" or not. If it is a thing then nominativ and ackusative cases are the same like in this example. What happens in ackusative case if the noun is of a kind (what do you call it in English/russian?) that forces acusative to change?

Adjective: чёрный Noun: дом (Masculine)

Normal Adjectives - Hard (“-ый”, “-ой”, “-ий” (but not “-ний”))

Nominative Case: чёрный дом

Accusative Case: чёрный

Genitive Case: чёрного

Dative Case: чёрному

Instrumental Case: чёрным

Prepositional Case: чёрном

  • As you probably could have guessed (and I have pointed out this more than once that) I am new to this forum. If you correct me or give me a reference I will adapt. When you just have an opinion (no reference) then I do not reflection about it because everyone have opinions nowadays. Someone else had a similar comment as you did and I started to accept answers.

The accusative case forms differ for animate versus inanimate objects. In the 2nd declension the accusative or an animate noun coincides with the genitive case, and the accusative for an inanimate object coincides with the nominative.

Nominative: Человек . Дом
Genitive: Человека . Дома
Accusative: Человека . Дом

The adjectives change their form to match the noun they define.
