Prospective um-clauses as syntactically unintegrated clauses

In this paper, the differences between two kinds of um-clauses will be examined. After showing that there is a semantic difference between purpose and prospective clauses introduced by um, I will prove this difference to be reflected in their respective clause linkage status by using several well-known criteria. While purpose clauses are subordinated, prospective clauses constitute a non-canonical clause type. Finally, I show how these syntactical differences could be modeled within a theoretical framework.
