(Greek - a system, an order) it is accepted to understand the section of grammar studying all sum of the rules concerning creation of the speech units differing by the sizes from a word as "syntax" - offers and phrases.
In traditional semiotics expanded interpretation of the term "syntax" - as the sums of rules of creation of difficult speech units from simpler units or even rules of creation of sign systems in general are applied. In the first case there are possible concepts of "intra-word syntax" and "syntax of the text", in the second the term "syntax" is not limited to a framework of verbal sign systems. Nevertheless, a part of linguistics, or the semiotics occupied with a research of syntactic units and laws has major importance of syntax its definition as. The syntax determines language ways of expression of fundamental abstract categories of an object, the subject, sign, a question, etc. by method of the hierarchical organization of speech designs.
In this sense the division of syntax and morphology is rather complicated by the specifics of a word as the subject of morphology having some hierarchical structure. Categories of a morphological research are connected with the frequency of use of value not to a lesser extent, than syntactic that led to emergence of the term "morfosintaxis". At the same time, the structure of a phrase or offer means much bigger degree of complexity, than structure of a word. Distinctive feature of the offer, in this sense, is its ability to unlimited complication. Specifics of syntax is the evident reflection of a creative component of language which is shown in continuous creation of new speech designs in the course of verbal communication at rather rare emergence of neologisms. One more determination of syntax as the fields of the grammar investigating generation of the speech - creation of an infinite set of phrases and offers from a final set of words is connected with it.
