The actuality of the present thesis

I.2.Flective languages
Meaning of sentence is defined by changing words (morphology). I mean all these suffixes, preffixes and many more stuff you must keep in mind. "дом" (home/house), "дому", "домой", "домом", "доме", "дома" etc... 
"идти" (to go), "идет", "идут", "пойдет", "шли", "пошли" etc.... 
It's not easy to remember. From the another side there are no strict rules of words order. 
You can say "Я иду домой" (I go home/I'm going home), "Я домой иду", "Домой иду я", "Иду я домой". Although first variant is more correct others are grammatically correct too. You can use second ("Ядомойиду") when answering question "Where're you going?". You can use third ("Домойидуя") when answering question "Which one of you are going home?" Still using first variant is
considered as a correct choice in any occasion of linguistic position. 


I.3.Synthetic languages
In linguistic typology, a synthetic language is a language with a high morpheme-per-word ratio, as opposed to a low morpheme-per-word ratio in what is described as an isolating language. This linguistic classification is largely independent of morpheme-usage classifications (such as fusional, agglutinative, etc.), although there is a common tendency for agglutinative languages to exhibit synthetic properties.
A member of a typological class of languages in which grammatical meanings are predominantly expressed by synthetic forms. Synthetic languages are in contradistinction to analytic languages, in which grammatical meanings are expressed by means of auxiliary words, and to polysynthetic languages, in which several nominal and verbal lexical meanings are combined within an indivisible complex that outwardly resembles a word.
The basis for the division of languages into synthetic, analytic, and polysynthetic languages is, in fact, syntactic; the division therefore intersects but does not coincide with the morphological classification of languages. The classification of languages according to synthetic and analytic features was proposed by A. von Schlegel (only for inflected languages); A. Schleicher expanded the classification to include agglutinative languages.
The morphemes making up a word in a synthetic language may be combined according to the principles of agglutination or fusion, or they may undergo positional alternations, for example, vowel harmony in Turkish. Synthetic forms occur in a significant number of the world’s languages. Since languages are not, in principle, typologically homogeneous, the term “synthetic language” is applied to languages that exhibit a sufficiently high degree of synthesis. Such languages include the Turkic, Finno-Ugric, most Hamito-Semitic, ancient Indo-European, Mongolian, Manchu-Tungus, some African (such as Bantu), Caucasian, Paleo-Asiatic, and American Indian languages.
Isolating languages
Synthetic languages are frequently contrasted with isolating languages. It is more accurate to conceive of languages as existing on a continuum, with the isolating pole (consistently one morpheme per word) at one end and highly polysynthetic languages (in which a single inflected verb may contain as much information as an entire English sentence with various words such as a noun, an adjective, and an adverb) at the other extreme. Synthetic languages tend to lie around the middle of this scale.
