The contrastive-linguistic, intercultural and cognitive-typological analysis of the English and Romanian advertising ecological discourse, requires a clear delimitation, for operational purposes, of the meanings of terms related to advertising. This necessity is determined, first of all, by the lack of parallelism between the "inter-paronimic" terms (false friends of the translator), following how the English terms correlate and what common interferences they have. We suggest clarifying several such aspects both separately, as distinct linguistic situations, and as “internal” forms of each of the two languages, which is likely to convince the speakers of the need to understand and use the correct constructions and forms.
