The article deals with the main structural and semantic features of simultaneity relations implemented in the economic discourse. The simultaneity relationship under study can be seen in the very essence of economic science and economic concepts, therefore it is bound to manifest itself and to be expressed in the language and linguistic categories forming the economic content. Thus, a large group of abstract names having predominantly deverbal nature can be distinguished. Such substantives are able to designate a situation synchronous with that represented by the main part of the sentence in a reduced form, which allows considering sentences with abstract names to be a specific form of expressing the taxis relation of simultaneity, characterized by its own specific features.
However, the first place among the structures in which simultaneity relations are implemented belongs to complex sentences with time clauses. Moreover, linguistic structures of the economic discourse in which the taxis meaning of simultaneity is implemented include sentences with homogeneous predicates, with participial, gerundial and other phrases, compound sentences, as well as simple sentences and sequences of independent sentences.
Specific features of the material under study also include convergence of semantic meanings in a complex sentence: conditional and temporal meanings, concession and time, reason and time. This is accounted for by the fact that the language is a system that is “rigid” and “soft” at the same time comprising transitive, intermediate phenomena that do not contravene the idea of the integral systemic nature of the language structure, but, on the contrary, demonstrate flexibility and mobility of the language. Therefore, "pure taxis", free from anything beyond the limits of chronological relations, is an abstraction that is far from linguistic ontology. Taxis cannot be considered irrespective of the complicating semantic elements mentioned above.
