Conceptual Metaphors and Image Schemas: A Corpus Analysis of the Development of the On Track / Off Track Idiom Pair

Abstract

Using the theoretical constructs of “image schema” and “conceptual metaphor,” this study examines the use and historical development of on track and off track as a pair of metaphorical idioms in American English. Specifically, this article is concerned with usage patterns and semantic changes of the expressions over the past two centuries in three American English corpora. We study the semantic features of the subject nouns as the “trajectors” and the diverse verbs used with the on/off track metaphors in order to uncover the main cognitive mechanisms underlying the use of the two idioms. The results of the study delineate how the development of the metaphorical idiom pair was largely motivated by PATH/FORCE conceptual metaphors based on image schemas and licensed by the Event-Structure Complex Metaphor; this demonstrates the important role of image schemas and conceptual metaphor in language use and development. The results also reveal that, in using metaphors based on image schemas, speakers/writers may activate very specific embodied images, and that context influences the use of the metaphorical idiom pair. Our results also support findings from previous corpus-linguistic theory-guided corpus studies of lexical/syntactical constructions, confirming again the vitality of this research.
