This 24min-long, cum-audio, presentation addresses the remarkable alternation involving frontable and unfrontable contrastive foci first examined in Bianchi (2013). The talk argues for focalization in-situ as a default, claiming that a left-peripheral FocusP anaysis is unable to account for the alternation. It also provides arguments in favour of Samek-Lodovici's (2015) analysis of focus fronting as well as a discussion of Bianchi et al's (2015) characterization of the properties of non-corrective, merely contrastive, foci.
