DMIP: A Method for Identifying Potentially Deliberate Metaphor in Language Use

This paper introduces the Deliberate Metaphor Identification Procedure (DMIP), a method for the systematic and reliable identification of potentially deliberate metaphor in language use. We take a semiotic approach to deliberate metaphor, and propose that, on a semiotic level, the distinction between potentially deliberate and non-deliberate metaphor hinges on the question whether the source domain functions as a distinct referent in the meaning of a metaphorical utterance. We present DMIP and illustrate the procedure in practice on the basis of the analysis of a series of real-world examples. We also report on inter-rater reliability testing. Finally, we discuss the implications of adopting DMIP as a tool for deliberate-metaphor analysis, and point out how this approach can contribute to the further development of Deliberate Metaphor Theory.
