The evolution of mathematical mentality and formation of numerals as parts of speech

The influence of mathematical mentality is defined by researchers as a main source of grammatical evolution of numerals. The universal semantic content of numeratives, associated with the expression of the mathematical idea of a number, really makes their purpose for a variety of languages rather similar. Evolving semantically, the systems of numerals in their lexical composition are unified by the principle of terminological systems. The unifying thread and the scope of their formation strictly define the syntax sequence of its components. The numerals are set in a single derivational model. The counting series, in which numerals perform their main function, is a special text. Its elements have a semantic and formal influence on each other. In the process of numeration, numerals tend to the state of maximum isolation from the other parts of speech, usually the nominal ones. The tendency is manifested both in their semantic and grammatical characteristics. At the same time, the examples given in the article, show that the interaction of abstract-mathematical mentality and grammar can result in formal transformations. Such transformations are strictly specific for each language and depend on a number of factors.
