Unlike the Finnish and Hungarian languages in which there are one and a half-two dozen cases in the Russian grammar they are allocated by only six. The terminations of the words standing in different cases I can coincide therefore for definition of a case it is necessary to ask the correct question to the checked word.
Instruction
1. To define a noun case, attentively read a phrase which part it is. Find a word to which the noun checked by you belongs, - from this word you will ask a question. For example, you were given a phrase "I love dogs", and it is necessary to define a case of a noun of "dogs". The word of "dogs" in this offer submits to a word "I love". Therefore, you will ask a case question as follows: "I love whom?"
2. To each of six cases there corresponds the special question. So, nouns in the Nominative case answer the question "who?" or "that?". To this case it is possible to substitute the auxiliary word "eat". For example, is (who?) dog. A question of a genitive case – "whom?" or "what?". To a noun in this case it is possible to substitute the auxiliary word "no". The dative case answers a question "to whom? / to what?" it is also combined with the auxiliary word "give". A question of an accusative case – "whom?" or "that?", and his auxiliary word – "to blame". Nouns in an instrumental case answer a question "with whom? / than?" are also combined with words "is created" and "happy". At last, prepositional case it is characterized following questions: "about whom?/о than?", "in whom?/в than?". One of the auxiliary words of this case is the word "think".
3. To define an adjective case, for a start it is necessary to find that noun or a pronoun to which it belongs. Having defined a case of this main word, you learn also an adjective case as adjectives will always be coordinated in a sort, number and a case with those nouns (pronouns) on which they depend. For example, in the offer "Kolya ate big pear" the noun "pear" is used in an accusative case therefore the case of the adjective relating to it "big" is accusative too.
