The grammar of temporal motion: A Cognitive Grammar account of motion metaphors of time

摘要

Recent groundbreaking work in cognitive linguistics has revealed the semantic complexity of motion metaphors of time and of temporal frames of reference. In most approaches the focus has been on the clause-level metaphorical meaning of expressions, such as MOVING EGO (We are approaching the end of the year) and MOVING TIME (both EGO-CENTERED, as in The end of the year is approaching and FIELD-BASED, as in Boxing Day follows Christmas Day). The detailed grammatical structure of these metaphorical expressions, on the other hand, has received less attention. Such details include both elements that contribute to the metaphorical meaning and those that have a non-metaphorical temporal function, e.g., tense and (central features of) aspect. I propose a model for the analysis of metaphorical expressions, building on earlier work in Conceptual Metaphor Theory and the framework of Cognitive Grammar (CG). I approach the grammatical structure of metaphorical expressions by analyzing the interplay between veridical and metaphorical systems of expressing temporal relations. I argue that these systems relate to two relevant conceptualizations of time. Veridical time (VT) is the non-metaphorical conceptualization of time, where the processual profile of the clause-level metaphorical expression resides. A metaphorical path (MP) is the metaphorical conceptualization of time as a path occupied by the metaphorical motion. A motion metaphor of time tracks the MOVER's changing position on the MP against VT. I show how metaphorical expressions based on a motion verb differ from those based on a prepositional construction in grammatical and semantic terms, and how tense and aspect contribute to the conceptualization of the motion scenario. I argue that tense grounds the metaphorical motion event with respect to the speech event. All the participants in the motion event, as well as the metaphorical path itself, are present in each subsequent configuration tracked against VT by the conceptualizer. Thus tense has a wide scope over the motion scenario with Ego's 'now' as a reference point, while Ego's 'now' cannot serve for grounding of tense. This is why expressions such as * The meeting is difficult ahead of us are not acceptable.
