Тhe processes of growth and decay are natural to development of language. So, the analytical form, a complex system of verb formation is developed in English, but the system of the declination and personal endings of the verb is decayed, the words from the vocabulary are dropped, the new ones are appeared by borrowing or tumors [2, 56]. While Ancient English was not so strongly inflected language ​​like Sanskrit, Greek or Latin, it had a complex system of declension and conjugation. Because nouns persisted case endings, many relationships can be expressed without the help of prepositions, in contrast to the modern English language.

The process of withering away of the inflections accelerated in the inflective Ancient English, extends from north to south, explained by the proximity in the dictionary against the conquerors and the Anglo-Saxon language, which could contribute to linguistic confusion with its usual consequences in the field of morphology [1, 134].

The peculiarity of Greek word formation was to preserve certain types of word formation, the presence, in many cases synonymous suffixes and prefixes and suffixes ambiguity. Parts of speech in the ancient Greek  differ in the way of word formation and activity of a word-formation process. So, derivative nouns have more verbal formations and adjectives – denominative; the names used suffixation, and the verbs in the main – prefixing.

Most Greek words are derivatives formed using archaic, productive or later productive ways of word formation. Archaic methods of derivation are prosodic derivation and flexion (morphological) derivation. The most productive way of derivation is an affixation, which has its own characteristics in the ancient Greek.

Turning to the inflection (morphological) derivation, we can say  following: the crossing processes of word formation and morphogenesis were typical for the Indo-European language. The relics of this state are preserved in ancient Greek. So, the endings ο / ε and α of the basics of nouns, in many cases could not only be an indicator of various types of declinations (morphological variability), but also the act as word-formation suffix that left a trace in the form of a significant number of doublets: τρόπος – τροπή, βόλος – βολή.

Some of them have the same value (for example, τρόπος, τροπή «turn”), and part has a difference in meaning, either in use (maybe it’s later distinction): morphological variation, being excessive, became accompanied by a semantic difference. Comp .: ‘ρόος «tax file» -’ ροή «wearing, harvest». [3, 218]. Comp. in Russian: цеп и цепь.

If we consider affixed derivation, then it includes suffixation: verbal nouns (indicating the protagonist – σωτήρ «savior» from σώζω «save», an action or state – δεσμός «node» from δέω «associate», the result of – γνώμη «knowledge» by γιγνώσκω «know», with a value of instruments or means – λύτρον «buy» from λύω «buy back»), denominative (with a value of quality – φιλία «friendship» from φίλος «other», pet names – βιβλίον «book» from βίβλος «book» magnifying – χείλον «wrasse (fish)» from χε ~ ιλος « lip », denoting the offspring of ancestors, parents Δανα ~ ις« Dana “from Δαναός «Danaets» denoting the place of action – ο’ινός «Wine Warehouse» from ο ‘ίνος «Wine», a man name of the area – Σύριος «Syrian” from Συρία «Syria»); adjectives formed from nouns – λίθινος «stone» from λίθος «stone» verbs – φυγάς «runaway» from φέυγω «runaway», adverbs – χθές «yesterday» from χθεσινός «yesterday»; adverbs and suffixes – ‘άλλοθι «elsewhere» from’ άλλος «other».

Thus, the cause of the historical transformation of Morphosyntax was the loss (to varying degrees) case forms, substitute synthetic means and paradigmatic order [4, 268]. Of course, this process is not instantaneous. On the contrary, it lasted for many centuries and was the result of many factors, including the following: 1) the tendency to active expansion of prepositions; 2) preference for a system of analytical forms of expression that talker felt more simple, predictable and regular than literary inflected; 3) some weaknesses declinable classes, as well as the presence of a number of tokens indeclinable; 4) certain phonetic changes, which led to the destruction of the classical image of the overwhelming mass of words.

The role of the preposition is not confined to formal syntactic function indicate what word grammatically subordinate to the other. It plays an important role pretext reported separately phrase (and through him, and often the whole sentence) its value, which specifies and summarizes the relationship “significant” words among themselves, [1, 37].

Grammatical prepositions perform the functions as former case inflections of English nouns, since flexion lost their semantic functions. Prepositions pass ratio toiletries (rare possession), instrumentality, destination activities and others. In this function are the prepositions of, by, with, to, for and to a lesser extent, partly formalized through, in, at, about, on in which the semantics of grammatical meanings occupy a subordinate place. In its content and grammatical function of these excuses hold a very special place in the English language and approach to the inflections of case.

Grammatical English prepositions role is obviously very important, because a number of inflections able to express grammatical meanings. In English prepositional turnover is almost inevitable element of a huge number of proposals. A number of relationships here can be expressed only prepositional turnover (the note was written by my sister with a pen the note was written by my sister handle). In terms of lexical prepositions make up the category of words and phraseological ambiguity of productivity is one of the first places in the language. On the other hand, the words form numerous series of revolutions of various prepositional syntactic and lexical content of the destination [1, 39].

There are different points of view about what kind of values ​​should be recognized as a pretext categorical [7, 14]. More often than not in the works indicated value relationship or relativity [3, 104; 4, 705; 6, 86; 7, 19; 8, 79]. However, the ratio is peculiar to other categories of words like service (unions, particles) and significant (pronouns, some adjectives). Generalized value prepositions with original local and portable adverbial values ​​reduced to deictic, index. The preposition as part of verb-noun syntagma indicates which of the spatial, temporal, causal, modal and others. Values ​​it expresses [5, 6].

The former functions of case inflections of nouns in English since flexion lost their meaning-function, perform grammar prepositions. But before it, let’s consider the category of prepositions. Aksenenko believes that “many excuses have bright lexical semantics and that there are three categories of prepositions, quite different in their lexical and grammatical characteristics: a pretext and that can contain values ​​relating to nature in all three categories. I should add that we consider excuses approach – removal, so select only the data values ​​prepositions.

1. Lexical excuses – “free” (the relationship space, movement and time), as in: He stayed at Middlepool for two years. They rehearsed from ten till two, when he sent them home to learn their parts and rest before the evening’s performance [9, 18]. But when he came into the office he was staggered by his office [9, 19].

2. Lexical excuses – “fixed” (abstract relations than of case), as in: He had guessed why Michael wanted to see him, and had gone the night before to see him play [9, 19].  Jimmy Langton quickly came to the conclusion … he would never be more than a competent actor [9, 20].

3. Grammar prepositions (former case relations), as in: But when he came into the office he was staggered by his beauty [9, 19].

Free excuses though not perform an independent function of the sentence, but appear in the proposal as significant components of the sentence. They communicate with other words, language is always temporary, to this case.

Fixed prepositions differ from free to those that transmit “no concrete relations space, movement and time and abstract” [1, 43]. His excuse lexical meaning fixed points or clarify the content of these relations.

Very often, one verb partially changes its value depending on the use of three different fixed prepositions. Coupled with the free prepositions decisive significance is almost always a meaning of preposition, not a “significant” word; with fixed prepositions is not the case, since the semantics of the verb or noun dominates the semantics of a preposition, which values ​​the general and vague.
