Control without a Subject

The aim of this paper is to develop a representation of control that does not require a PRO-subject. I first analyse obligatory control using a de-compositional analysis of ?-roles, according to which ?-roles are divided into two selectional requirements. The resulting theory makes the same predictions as one based on PRO, yet avoids dependence on this ill-defined empty category. I then concentrate on Icelandic, tackling agreement phenomena in infinitival clauses. Again no PRO is necessary to cater for the data, which receive a uniform account using the mechanism outlined in the first half of the paper.
