Metaphor as a common element of scientific and fictional texts

The article is dedicated to the study of metaphor as a term of metalanguage and to its ability to serve as a common element of both scientific and fictional texts. Topicality of the article is grounded by the fact that nowadays special terms are widely used not only in scientific but also in fictional texts. The problem consists in the fact that so far the scientific term has been regarded as unambiguous and such its properties as connotative character, emotivity, pragmatism, evaluative character and anthropomorphic character have been neglected. As concerns the special terms of some domains scientific researches affirming an opposite idea are being created when the amount of studies investigating the terms of linguistic metalanguage is still insufficient to consider this problem to be solved. In the article the opinions of different linguists are given. These opinions rest upon propositions of cognitive science and on reception of metaphor as a tool of world cognition. The article also dwells upon stages of term formation. On the ground of study of such a term of linguistic metalanguage as metaphor and of different terms that serve as units of speech production the idea is affirmed that terms can be full members not only of scientific language but also of fictional one. The terms of linguistic metalanguage may become polysemantic and evaluative in fictional texts when colloquial words are liable to metaphorization and may perform functions of linguistic terms.
