How does the noun change?
You can say that the noun is one of themain parts of the speech of the Russian language. Recall that this is an independent part of the speech, answering the questions: who? what? It follows that the noun denotes things animate and inanimate. And how does the noun change, by what criteria?
The noun has morphological features. The word "morphology" (from the Greek "morphe" - form) means a system of forms of changing words in some language. To these attributes, in addition to animality, there are also naming (own, common), declension, gender, number, case. In noun, the noun changes in numbers and cases.
Just note that by birth (as many think)the noun does not change. It simply refers to one of the genera - female, masculine or to middle. Determine belonging to the genus with the help of pronouns:
- male - he, my;
- female - she, my;
- the average is it, mine.
Number of nouns
As a rule, nouns are used both in the singular and in the plural. It depends on how many words are spoken about. For example: ship - ships, road - roads, river - rivers.
But there are words, the form of which assumes only a single number. These are collective names, qualities, signs, actions, proper names: children, blue, Volga, etc.
Words used only in the plural are compound objects (trousers), intervals (weekdays), actions (troubles), games (syllables), geographical names (Andes).
Change by case
This change is called declension. The six cases of the Russian language are answered by certain questions:
- Nominative case: who? what? (ocean, oceans).
- Genitive: whom? What? (ocean, oceans).
- Dacia: who? What? (the ocean, oceans)
- Accusative: Whom? what? (ocean, oceans)
- The instrumental: by whom? than? (oceans, oceans)
- Proposal: about whom? about what? (about the ocean, about the oceans).
Defining the case of a noun, put the question from the word to which it refers.
So, remember: the nouns change in numbers and cases.
