The study of the inverse flow of grammatical metaphor in the process of popularization of scientific articles in the mass media

The present paper on the reverse flow of Grammatical metaphor has surveyed the usage of grammatical metaphor in two varieties of Scientific articles- medical academic articles and medical popularized articles- with the same topics.This subject was chosen to be studied aiming to discover the differences between language structures that scientific journalists and academic authors use to transfer scientific ideas and issues in their articles. Grammatical metaphor is the concept that Halliday uses in Systemic functional grammar and it means changing one grammatical category to another; in this process verbs and adjectives change to noun and clauses to nominal groups as well. This process leads to increase of lexical density and also complexity and abstraction of the text. Findings of this study show that authors of popularized scientific articles to publish their writings in mass media, usually simplify the grammatical structures in addition to lexicon. To reach this aim and also to justify simplified texts with the normal and congruent process of transferring meanings via language, avoid using grammatical metaphor in their texts.
