I would like to propose an ideal mechanism for V2 adopting the guidelines of the Cartography of Syntactic Structures (Cinque & Rizzi 2010; Rizzi & Cinque 2016). I consider V2 as a sum of "residual" V2 (Rizzi 1991). Each "residual V2" targets a different functional projection in the LP in a Spec-head configuration, similar to the Wh-criterion. The inflected verb undergoes movement through all the activated LP heads until it lands in the highest one, giving raise to V2 order. After having presented Cartographic guidelines and discussed the drawbacks of mainstream analyses concerning V2, I will develop a Criterial V2. Assuming Cartographic guidelines, the natural hypothesis is to adopt the proposal in Travis (1984) and Zwart (1997), in which the “canonical” subject remains in the IP, within a Cartography of Subjects (Cardinaletti 2004). I will bring evidence from Swiss Romansh varieties and Icelandic. Finally, I propose that scrambling means movement to the LP, without a “bottleneck effect” in SpecFinP: the ungrammaticality of certain patterns may be due to standard fRM effects, as it is the case for the lacking of multiple topics in English (Haegeman 2012; Rizzi 2013).
