Constructions are not predictable but are motivated: evidence from the Spanish completive reflexive

Abstract

Abstract Many researchers seem to think that Construction Grammar posits the existence of only wholly idiosyncratic constructions. However, this misconception betrays a deep misunderstanding of the approach because it glosses over the fact that constructions rarely if ever emerge sui generis. Rather, Construction Grammar aims to balance the fact that some linguistic uses cannot be fully predicted from other well-established uses with the fact that extensions of a construction, while not predictable, are motivated by other senses in the constructional network. This paper illustrates this idea by providing an analysis of the Spanish completive reflexive marker se.
