Abstract:

This paper expounds the cognitive structure of metaphor in option terms,introduces the metaphorical nature of vocabulary and the metaphorical phenomenon of option terms,and also introduces two innovative dimensions of dynamic mapping and cultural adaptation.Based on analyzing the metaphorical source of option terms and the cross domain mapping mechanism,this paper constructs a term analysis framework to adapt to market changes and cultural differences,and proposes a Dynamic Cultural Adaptation Metaphor Model (DCAMM) and strategies for improving the comprehensibility of option terminology.

Key words: option terminology, cognitive metaphor, Dynamic Culturally Adapted Metaphor Model(DCAMM), understandability
