The notion of pro control in german participle clauses
Abstract
Another important issue in research of control is the co-indexation of antecedent and PRO. The obligatory control of PRO implies a special syntactic mechanism between antecedent and PRO, while the relation between antecedent and PRO in nonobligatory control is conditioned by pragmatics. There are 4 different approaches to the mechanism responsible for obligatory control: 1) control is predication; 2) control is binding; 3) control is movement; 4) control is agree.
