Have you ever been bothered by cases? There was no case in the notebooks of your son or daughter, "shot" in red in many places, case endings were corrected ? Rare people with an innate sense of language and linguistic instinct do not stumble when declensing cases of nouns, especially in school childhood.
With the help of case variability, a noun is put into the necessary form with which other words that name an object, sign or action are consistent. This property allows nouns within the grammar rules of the language to combine with other nouns, as well as adjectives and verbs, creating phrases and sentences. The nominative case is the first of six, the initial form of nouns that name persons, objects, phenomena, etc. The names of animate objects can be asked: "who?" To inanimate nouns in this case, the question can be posed: "what?"
The nominative case is the grammatical case form inherent in the subject-producer of the action or the carrier of the state, attribute in the syntactic construction. The name of the subject is an independent grammatical form, i.e., a question is posed from him to the dependent word of the phrase included in the sentence.
The nominative case is usually used correctly. There are errors associated with its use instead of the form of the instrumental or
genitive cases. For example, sometimes they say: "There is nothing to go with three hundred dollars," instead of "There is nothing to go with three hundred dollars." Or: "You need to overcome more than five hundred kilometers" instead of "You need to overcome more than five hundred kilometers."
The nominative case in words in the singular in Russian grammar is indicative of the absence of an ending, or rather, the presence of the so-called zero ending in many nouns belonging to the masculine gender, for example: poplar, finger, table. And for feminine nouns and masculine words denoting names or kinship there are endings a, s, for example: feminine - girl, winter, cap, masculine - Vova, uncle, Kolya, dad.
The nominative plural of these nouns gets the ending -and, for example: girls, winters, caps, uncles, dads. Although the plural of masculine nouns can get the endings -a, -i, for example: teachers, professors. The form of the nominative plural is also formed with the help of an additional sound at the base and ending i, for example: leaf - leaves, son - sons (a dividing soft sign appears on the letter ). It happens that the plural ending joins a truncated basis, for example: Christian - Christians.
The range of syntactic functions of the nominative case is limited by the fact that it is not controlled by the verb and is not combined with prepositions. In order to correctly form case forms, even the simplest, you need to be a native speaker and know the rules of word formation.
