On Metaphor and Metonymy

This article proposes that metaphor and metonymy should be considered as "activation of target domain by source domain" rather than "mapping or projection".Based on this viewpoint,it argues that there is no clear-cut distinction between metaphor and metonymy regarding "activation".Then,it classifies metaphor and metonymy into two types: single activation and multiple activation,and divides single activation into three sub-types: "similarity activation","whole-part activation" and "cause-effect activation".Finally,the paper analyzes the "hen+noun" structure and "de" structure in Chinese in terms of metonymy.
