In Russian the nouns change not only on number, but also, unlike many foreign languages, change on cases. In total their six, the noun expressed in any given case answers various question.
Instruction
1. Read the text. Allocate in it a subject. It is the principal part of the sentence and answers the question "who?" or "what?". If the noun, but not, for example, a pronoun acts as a subject, it is surely expressed in the Nominative case. For example, in the offer "dogtooka trace of a fox" the noun "dog" is used by in the Nominative case and is a subject.
2. Ask an auxiliary question to other nouns in the offer. Begin with the questions "whom?", "what?", by which it is possible to define whether the noun in a genitive case is expressed. In a phrase "in shop there were no apples" such word is "apples".
3. Define whether the word in a dative case is not necessary, for this purpose ask a question "to whom?", "to what?". For example, in the offer "it gave a notebook to the teacher" the noun "teacher" is expressed in a dative case.
4. Do not confuse an accusative case with imenitelny though both of them answer the question "what?" for inanimate objects. Check yourself the question "whom?". Besides, the noun in an accusative case always performs function of addition in the offer. In a phrase "it gave me the remote controller from the TV" a subject the pronoun "it", and addition in an accusative case the word "remote controller" is.
5. If the noun answers the question "whom?" or "than?" it can also be used with the word "it is happy …", so it has an instrumental case. For example, in a phrase "the song is written by the unknown author" in this case the last word is used.
6. Ask the question "about whom?" or "about what?" or use the auxiliary word "think about …". The noun in the offer answering this question has a prepositional case and, as a rule, costs after a pretext "about" or "in". For example, "the boy told the grandmother about classes at school". The prepositional case in this phrase has a word "classes". It is used with a pretext.
