A note on root projection and labelling
This paper identifies a problem with a hypothesis put forward in Chomsky (2013) in relation to his labelling algorithm. Chomsky suggests that category-neutral roots do not qualify as labels and cannot project. However, I provide evidence that the derivation of particle verbs involves the projection of a category-neutral root, which has merged with (a projection of) the particle. It follows that Chomsky's hypothesis has to be rejected.
