Exploring vagueness: Preposition alternation in Spanish

This paper aims at showing the relevance of cognitive semantics in the study of linguistic units whose conceptual import tends to be underresearched within formalist frameworks. Specifically, I focus on the alternation between the prepositions con 'with' and de 'of' in the change-of-state variant of the locative alternation (e.g., cargar el camión con/de heno, lit. load the truck with/of hay). I show that although the con- and the de-constructions share many semantic properties and they can refer to the same conceptual content, experimental-based cognitive semantics offers powerful tools to elucidate subtle shades of meaning that might remain opaque in formal semantic theories.
