Locative alternation in Proto-Indo-European. A Lexical-Constructional approach to the morpho-syntax and semantics of polysemous roots (PIE *leu̯g-, *u̯el-, and *pleh1-)

I argue for the reconstruction within Proto-Indo-European morpho-syntax of the phenomenon of “Locative Alternation”, i.e. the alternation for the same verb between a locatum-as-object construction (e.g., English spray paint onto the wall) and a location-as-object construction (e.g., English spray the wall with paint). Drawing inspiration from Iwata’s (2008) lexical-constructional approach to the phenomenon, I discuss its possible relevance to the reconstruction of the morpho-syntax and semantics of PIE verbal formations belonging to three PIE polysemous roots, namely *leu̯g- ‘bend, make bent, twisted, not straight; enclose’, *u̯el- ‘roll round, coil; enclose, enfold’, and *pleh1- ‘be abundant, much; be full, filled’.
