Initiating from Martinich's classic papers in 1980 and 1984,this paper explores whether the interpretation path of metaphor in pragmatic theories is accessible.Taking Grice's Conversational Cooperative Principle as an example,this paper reveals that metaphors are fundamentally pragmatic rather than semantic.The expression of metaphorical sentences is the result of the action of the metaphorical mechanism,not the reason for the feasibility of metaphors.Recontextualizing metaphors into a more universal and inclusive theory of language use enriches the current cognition-dominated research of metaphor theory and contributes to the construction of a more heuristic framework of metaphor studies.
