Under the framework of cognitive linguistics, this paper constructs a dynamic model of English semantic field with cognitive explanatory power, and explores the mechanism of lexical evolution. By integrating the philosophical view of experience and the mechanism of second language acquisition, a three-level cognitive processing mechanism of “perception-schema-category” is proposed, which explains the psychological basis for the formation of lexical networks and the cognitive drivers of semantic evolution. Experiments show that the model has significant advantages in predicting the structural characteristics and historical evolution of English near-synonymous lexical clusters. The study also developed a cognitive-driven vocabulary teaching method, which significantly improved vocabulary retention and semantic output accuracy by activating learners' perceptual experience and metaphorical mapping training. The empirical analysis reveals that English vocabulary changes over time according to the principle of “cognitive economy”, with high-frequency semantic nodes forming core clusters through conceptual integration and low-frequency semantics becoming marginalized. The semantic field model proposed in this study not only improves the theoretical system of cognitive linguistics, but also shows practical value in machine translation and computational linguistics.
