Professor Wang Yin has proposed a new theory: Embodied-Cognitive Linguistics. The core principle of this theory is “Reality-Cognition Language”; that is, both our mind and our language originate from embodied experience and cognitive processing. Thus, the study of language must be combined with social and psychological factors. This paper, based on Wang Yin’s Embodied Cognitive Linguistics, analyzes the motivations of overall quantitative coordinate constructions in Chinese idioms. The aim is to explore how such constructions in Chinese idioms derive their overall quantitative meanings from metonymy and prominence of meanings.
