Abstract: The article examines the processes of development of scientific theories and conceptual and terminological apparatus of two types: at the conceptual level (conceptual derivation in the processes of obtaining new scientific knowledge) and at the level of their linguistic re-presentation - language derivation in the creation of new scientific formulations and terminological apparatus. The author also outlines the criteria of effectiveness of these derivational processes of conceptual and linguistic types in the domain of scientific research.
