The book deals with the analysis of the expression of Grammatical Relations in spoken Italian verbless sentences. Unlike previous studies, this corpus-driven research aims at showing that it is possible to identify Grammatical-Relations in verbless sentences and that their encoding marks are non-canonical, as it occurs in verbal sentences which present non-prototypical arguments. Moreover, it demonstrates that the spoken language is a privileged field of observation for the analysis of systemic grammatical phenomena which are not always evident in written language.
