Styling itself a science, socialist economics or „scientific socialism‖, based on the Marxian theory of value, produced (under the influence of Russian models mainly) in Romanian an ample set of linguistic units (both simple and complex/syntagmatic) that were – along the nearly five decades in which the socialist regime held in Romania – recorded in specialised dictionaries as terms. Of this set, some belonged to the initial Marxian theory (plusvaloare, plusprodus, timp de muncă socialmente necesar etc.) as defined by the creator itself, while others were coined by his followers (deosebiri esenţiale dintre oraş şi sat în capitalism). The present papers analyses the discourse of definitions of the latter excerpted from specialised dictionaries in order to disqualify some of them as terms since they do not meet the requirements of a coherent scientific terminology and to present such definitions as samples of ideological discourse that display instances of polarized thought (based on the categories US and THEM) and relying on group representations in relations to other groups (centering round issues such as Who are we? What is good or bad? and How we relate to other groups? Although the discourse of socialist economics along with socialist propaganda has been analysed from a rhetorical point of view (to quote only Françoise Thom, 2005, Limba de lemn, Humanitas, Bucureşti), an analysis from the terminological point of view has not been performed yet. The present study may contribute to establishing more accurately the relationship between the current terminology of economics and the pretense of the socialist version.
