 Hello, this unit discusses the primary consequences of case syncretism with regard to external syntactic operations, that is, operations that may insert, delete or extract material from sentences. In the virtual session, we will first discuss and exemplify Claude's external operations. We will then discuss the effects of the weakening of the present-day English case system and will eventually focus on the effects of case syncretism on movement rules. The mastery worksheet is a dynamic multiple-choice test with several questions about operations such as raising, gapping or specific rule constraints. Not that easy, but after the virtual session you shouldn't encounter any problems anymore. Well, in the practical, a typical syntactic one uses data, sentences that exhibit all sorts of Claude's external operations, ready for analysis. The whole unit may be challenging, but if you make use of all its options at the same time, highly rewarding.
