[citation needed] The term raising has its origins in the transformational analysis of such constructions; the constituent in question is seen as being "raised" from its initial deep structure position, as the subject of the embedded predicate, to its surface structure position in the matrix predicate/verb.
Raising-to-object predicates overlap to a large extent with so-called ECM-verbs (= exceptional case-marking).
The raising-to-subject verbs seem and appear are similar insofar it is difficult to view them as predicates.
The following trees are illustrative of the type of structures assumed for raising-to-object predicates.
A number of empirical considerations support the relatively flat structures shown here.
That is, empirical considerations support the position of the "raised" constituent as a dependent of the matrix predicate/verb.
Despite the fact that structures assumed for these different predicate types are essentially the same, there is a major distinction to be drawn.
The distinction between raising-to-object and control predicates is identified using the there-insertion diagnostic.
