Within the scope of the EndoTerm project, described in more detail in (Carvalho, Costa, & Roche, 2016; Carvalho, Roche, & Costa, 2015), this paper aims to explore Terminology's key role in supporting one of the fundamental forms of concept representation-the definition-, namely by assuming a double dimensional perspective in which the conceptual backbone supports the writing process. In particular, the article will focus on how conceptual information (i.e. the concept's position in the concept system, its characteristics, as well as the relationships linking it to other concepts) can be organised into a template-like format which would constitute the foundation of the natural language definition drafting process.
