preposition in Russian - it's part of speech, which is necessary in order to express the syntactic links of words or parts of speech.It does not have its own remarkable value, it is therefore considered part of official speeches.
In Russian, there are two categories of words: non-derivative and derivative prepositions.
With the first all is clear.They were formed in the course of the evolution of language, are short words that can not be confused with other parts of speech or wrong to write them.They usually consist of a single word.
Offers prepositional non-derivatives in our speech occupy a significant place.For example: Arriving at six.Look at this house.I can not live without you.Walk along the edge.Tell about the new film.
Derived prepositions in Russian, too, are common, but to define them, and, especially, how to write, much harder.On the value they can also be temporal, spatial or causal.
Derived prepositions - preposition, which were formed from other parts of speech.Their momentous importance and morphological characteristics were lost for one reason or another, with only the syntax.They are most often used with a specific case.Unlike the significant parts of speech can be using the issue.This is done like this.
front of my house built school. build (where?) In front of the house.The word "contrary" does not have its own values, in this case it is - Derivative excuse.
I live in front of the new school. live (where?) Opposite (of what?) School.The word "opposite" in this case has its own lexical meaning, but because it is - an adverb.
Derived prepositions as derivative, may consist of a single word (simple) or several (components).For example: During the investigation revealed new details (composite).Because of the rain canceled the trip.(Simple).
Derived prepositions are:
- denote a certain period of time. sun baked with great force in the week.In the course of the investigation it is twice committed serious mistakes. preposition "during" and "within" refers to the time period and are only written separately.
- be close in value to non-derivative preposition due.It concerns an excuse "because" and the preposition "in mind.""As a result" as an excuse is always written only one word.Compare: trip canceled due to rain.Walk canceled due to rain.
preposition "in sight", in contrast, is written separately. Due to illness, he does not go out of the house.(Because of illness, he does not go out of the house).
- close in value to the combination of "whatever."This refers to a derivative of the preposition "in spite of", which is always written together.Compare: we went into the forest in spite of the weather.We will go into the forest, regardless of the weather.
- used to mean a pretext "on." We agreed about the extra classes.(On the other classes). preposition "about" is always written together.
- other examples. He's gone through and bowing from the waist. Gone (how? How?), And because of bowing.That is the gerund, synonyms say thanks - saying thank you.Bowing - bowing. Blagodrya to the decision they won. (because of the adoption ....)
Naturally, this is not all derivatives of prepositions that are used in the Russian language: These are just a few of the most common.
In order to properly determine what part of speech is the right word (and to determine its correct spelling), it is possible to choose the parts of speech homonymous synonyms.
example. I put money in a bank account. In this case, the expense - a letter of credit, savings book, ie,noun.Therefore excuse (at) + noun (expense) are written separately.
I agreed about the repair ."As for the" = "o" (arranged for repairs).So it derived an excuse, it is written together.
