As with the larger enterprise of cognitive linguistics of which it is a part, cognitive semantics is not a single unified framework. Those researchers who identify themselves as cognitive semanticists typically have a diverse set of foci and interests. Nevertheless, there are four guiding principles that collectively characterise a cognitive approach to semantics. These are: (1) the thesis of embodied cognition ; (2) the thesis that semantic structure reflects conceptual structure ; (3) the thesis that meaning representation is encyclopaedic ; and (4) the thesis that meaning construction is conceptualization.
