Abstract
abstract: This paper is concerned with multiple source left branch extraction in Bosnian-Croatian-Serbian, where left branch elements of multiple NPs are extracted. It shows that while multiple source left branch extraction is possible, it exhibits ordering restrictions. It demonstrates that these locality effects are based on an important fact that has also been noticed on completely different grounds for Case in left branch extraction by Dadan (2020): left branch elements enter feature-sharing with the elements they modify not in their base position, but after they undergo movement. It is argued that the observed locality effects can be accounted for in a system based on Bošković's (2007) proposal that movement is driven by the presence of an uniterpretable u K feature on the moving element, as well as Bošković's (2020, 2021) proposal that u K disrupts labeling (Chomsky 2013).
