Based on the analysis of the language samples drawn from the British National Corpus, the present paper adopts network model approach in cognitive grammar to investigate the polysemy of the preposition under. It is found that the spatial sense, the trajector below the landmark, exerts the prototypical effect on the semantic construction of under. By employing two categorization relationships, the central sense yields non-spatial senses, such as influence, covering, less, and undergoing a process, in aggregate constituting a semantic network of under. The paper proves the validity of the schematic network model in cognitive grammar, further demonstrating that a polysemous word is structured in a complex category with interconnected senses.展开更多
