According to the communicative-functional approach to translation any translation is made by applying a certain translation strategy and a number of relevant tactics. When choosing a translation strategy, a translator is supposed to define the goal of translation on the basis of a complex analysis of a communicative situation of specialised translation. One of the strategies is the strategy of tertiary translation.  In the research paper by establishing a communicative situation of specialised translation requiring the strategy in question the author attempts to ascertain translation tactics which provide its successful implementation.
