What's in a dialogic construction? A constructional approach to polysemy and the grammar of challenge

Abstract

In this paper we address lexical polysemy in a constructional perspective, arguing that each of the conversational meanings we identify for Modern Greek ela (2^nd person singular imperative of the verb erxome ‘come’) is appropriately modeled as a conceptual gestalt of formal (including prosodic) and semantic-pragmatic properties. In turn-initial position, ela is used to challenge a preceding utterance; we show that the variations in the kind of challenge expressed are systematically tied to the word that follows ela, the speech act force and the sentence type of the preceding utterance, and finally prosodic and textual cues. To the extent that these varieties of conversational challenge are conditioned by particular contextual features, we treat them as a family of related constructions whose common features can be captured in the form of a generalized ela construction abstracted from the different sub-patterns. Our analysis thus demonstrates the appropriateness of a constructional framework for dealing with the different kinds of parameters involved in dialogic meaning and strongly suggests that at least some of the variation inherent in discourse is amenable to a grammatical description, so that sentence-level and supra-clause patterns can be analyzed in a uniform way.
