Terminological dependency refers to the relations between the specialized terms of different languages when these relations are asymmetrical or hierarchical, i.e. linguistic subordination. In EcoLexicon (http://ecolexicon.ugr.es), a multilingual environmental knowledge base, and in its lexicographical counterpart MeteoTrad (www.meteotrad.com), there is a dependency relation between English and the rest of the languages. In this paper, we analyse the degree of dependency of a series of specialized English terms in relation to other terms in Modern Greek. These examples reflect the impact of English on the Greek language in certain subdomains of the environment. Paradoxically, Greek is still used to designate new concepts that the Greek community itself imports (αντιδάνεια, Rückwanderer, or “remigrant terms”). In Greek, this leads to morphological and conceptual adaptations as well as clashes in both general language words and specialized terminology. An explanation of this phenomenon is important for terminology theory since it can shed light on the specification and evaluation of hierarchical relations that underlie conceptual structure in different languages
