 For NSM, word meanings can be exhaustively represented with a metalanguage appealing exclusively to the combination of primitive linguistic particles. Conceptual Semantics (Jackendoff 1983, 1990, 2002) proposes a more open-ended approach. According to Conceptual Semantics, word meanings are essentially an interface phenomenon between a specialized body of linguistic knowledge (e.g., morphosyntactic knowledge) and core non-linguistic cognition. Word meanings are thus modeled as hybrid semantic representations combining linguistic features (e.g., syntactic tags) and conceptual elements grounded in perceptual knowledge and motor schemas. For example, here is the semantic representation of ‘drink’ according to Jackendoff.
