ABSTRACT
This chapter argues that Comp-trace (C-t) effects can be derived from different features on Fin° and by positing variable positions in the complementizer domain. It presents Boeckx' account of that-t effects in English. The chapter extends this theory to the Scandinavian languages. It includes a short discussion of extraction from embedded V2 clauses. The chapter summarizes the that-t parameter to a few other complementizer effects. It discusses relative clauses, and shows that they speak in favour of the C-t parameter. The complementizers in relative clauses are different from the ones in complement clauses. In particular, the chapter suggestes that Fin° has an EPP feature in relative clauses. The differences between various clause types and various C-t effects have all been connected to whether the complementizer lexicalizes Force° or Fin°, a difference related to lexical items. C-t-effects can be given a strictly syntactic analysis, which is a good argument in favour of a syntactic treatment of C-t-effects.
