 In the same vein as Frame Semantics (more on the parallels in Clausner &amp; Croft 1999), Langacker’s Theory of Domains argues that our understanding of word meaning depends on our access to larger knowledge structures called domains. To illustrate the notion of a domain, consider the word ‘diameter’. The meaning of this word cannot be grasped independently of a prior understanding of the notion of a circle. According to Langacker, word meaning is precisely a matter of “profile-domain” organization: the profile corresponds to a substructural element designated within a relevant macrostructure, whereas the domain corresponds to the macrostructure providing the background information against which the profile can be interpreted (Taylor 2002). In the diameter/circle example, ‘diameter’ designates a profile in the circle domain. Similarly, expressions like ‘hot’, ‘cold’, and ‘warm’ designate properties in the temperature domain. Langacker argues that domains are typically structured into hierarchies that reflect meronymic relations and provide a basic conceptual ontology for language use. For example, the meaning of ‘elbow’ is understood with respect to the arm domain, while the meaning of ‘arm’ is situated within the body domain. Importantly, individual profiles typically inhere to different domains, and this is one of the factors responsible for the ubiquity of polysemy in natural language. For example, the profile associated to the word ‘love’ inheres both to the domains of embodied experience and to the abstract domains of social activities such as marriage ceremonies.
