Russian is among the languages in which there are cases.However, if they were not, it would be used other pointers function words in sentences such as prepositions, postpositions, and word order.
Traditionally, the school program in the Russian language is studied six cases, linking words in a sentence and indicating their syntactic role.The decline occurs by changing the endings of nominal parts of speech: nouns, pronouns, adjectives and numerals.
To each of them you can ask a question, to distinguish one case from another.In addition, there are additional words, it helps with the decline.For example, the prepositional a word helpers "think", "dream", "feeling sorry" and declensional question "whom?", "To whom?", "What?", "What?" With suitablepretexts.
He has quite a different meaning.If prepositional linked to the question "for whom?", "What?", It can be consistent with both verbs and nouns.That is, it is like priglagolnym and priimennym.
Priglagolny used various pretexts.For example:
a) "about", "About" - to dream about a vacation to think about the salary;
b) "on" (has a value "after") - at the end of school, after receiving the parcel;
in) "under" (to indicate orientation or circumstances) - live in the manor house, including in theater of the department, be present at the examination;
d) "in", "at" signs as the place or object, if something or someone is within - to live in the city, be driven into the woods, sit in the hall, located in the courtyard, noted in his eyes;
e) "on" as a pointer to the surface - in the East, the sun, standing on the shore, lying on the couch;pointer location - to be at work, to be in a responsible position, to study at the Faculty of Philology;pointer to an object on which to perform actions - to focus on solving the problem, focus on the most interesting place;status indicator, circumstances or conditions that accompany the action - be retired, to be on vacation;pointer to the object, which is an instrument or material, as well as a pointer to the time of action - to ride a bike, cook in butter, to play the violin.
agree with him also a plural noun.For example: the life in the cities.
Priimenny prepositional used with nouns and verbal words, managers possessive case - a report on Russian art, the principles of the fight against smoking.
priimenny often used excuses such as "in" and "on" and the preposition "on" if you want to designate an indication or quality of the subject property.For example: sheep fur coat on, chronicle of a leather-bound, the horse has four legs.
happens that students correctly use prepositional case, the end of the confused.For example: "I miss him," instead of the correct version of the "miss him.""It gets on" rather than "to hit him."
If the student confuses prepositional case with the other, then he needs practice in the declension of nouns and other parts of speech.The most important thing - to stress during exercise and remember the end, which often depend on a word used any pretext.
