ABSTRACT
Concepts are one of the most signicant notions for the study of thought and language. They are “the most fundamental constructs in theories of the mind” (Laurence and Margolis, 1999, 3); they are at the root of cognitive abilities such as categorization and understanding and they constitute the primary building blocks of ontologies and linguistic systems. Therefore, it is reasonable that they have attracted the intense interest of many scientic elds, such as philosophy, linguistics, cognitive science, conceptual analysis, etc. During the centuries of studying concepts, different theories have been formulated regarding the ontological status of concepts, their nature, their structure, their relation to natural language, etc. (Laurence and Margolis, 1999; Margolis and Laurence, 2006).
