English motion and progressive constructions, and the typological drift from bounded to unbounded discourse construal

Recent psycholinguistic studies have revealed an important distinction in narrative discourse between bounded and unbounded language use. Bounded language use is typical of Germanic languages other than English and involves the holistic presentation of situations, with clauses construed as self-contained units attaining a point of completion. Unbounded language use, in turn, groups events into larger complexes of roughly simultaneous events, each event of which is still open when the next one begins. This contrast between English and the other Germanic languages has been accounted for by the claim that English began its history as a bounded language, but shifted to unbounded following the decline, from the fifteenth century onwards, of the Verb-second (V2) constraint on word order. According to this hypothesis, the loss of V2 made possible the grammaticalization of the be progressive, a device that encourages unboundedness. The present article expands on this line of research and examines seven constructions which developed at around the same time and which together are taking English in the direction of unbounded construal; it is argued that the drift in English from a bounded to an unbounded system may have been instigated by the contact situation between Old English speakers and Old Norse speakers in the Danelaw area.
