From verb to New Event Marker: another look at the Hittite pai- and uwa- constructions

In Hittite, deictic motion verbs pai- ‘go’ and uwa- ‘come’ may co-occur in a monoclausal structure with a second verb that carries the lexical meaning. As yet, their exact function remains obscure. I argue that motion verbs involved in such construction underwent transcategorization and function as New Event Markers. I show that this development is best explained as an instance of constructionalization involving both the motion verbs and the second verb in the clause, which is based on a pragmatic inference arising when motion verbs were used without a spatial complement. Either motion verb contributes a different semantics to the construction based on the different perspective regarding the deictic center identified by the ego, whereby pai- ‘go’ (motion originating from the deictic center) marks an event as close in time and controlled, while uwa- ‘come’ (motion originating outside the deictic center) indicates distance in time and possible lack of control.
