The terminological variation has been the object of several studies on Terminology in recent years. With the fact that variation is an inherent property of the term and that it can manifest itself in any field of knowledge (CABRE, 2008), the new theories of Terminology have studied this phenomenon taking into account functional, contextual and also cognitive factors. In this sense, the present investigation aims to analyze the phenomenon of the denominative variation in the field of Tourism, using the dictionaries Senas, Salamanca, and Diccionario de espanol para extranjeros as its corpus. In order to do so, we consider a methodology that consists of semantic analysis to establish the specification pattern and the intraterm relationships of these variants (KAGEURA, 2002).
