Synchronic and diachronic analysis of prepositional multiword modifiers across Romance languages

Lexicological and lexicographical studies on multiword expressions in Romance languages have significantly increased in recent years. Even though some attention has been paid to Multiwords functioning as adjectives and adverbs, the structural and the functional relation between them has not been clarified yet.Employing both a qualitative and quantitative approach, this corpus-based investigation aims at exploring the diatopic distribution and the evolution of Romance multiword lexemes having the form of a prepositional phrase and the function of an adjective or/and an adverb (or both functions). According to data taken from corpora of Latin, Old Italian, Old Spanish and Middle French, this contribution investigates the relationship between the different degrees of schematicity and the productivity of this kind of multiword lexemes in order to highlight the evolutional path and the diachronic/diatopic principles engaged in the multiword modifying system across the different Romance languages taken into consideration.
