This paper examines the use of causative verbs with two kinds of finite complements in Middle English (ME): a simple finite clause (V+that) and one involving both a finite clause and a separate NP (V+NP+that). I attempt to determine in which contexts these structures appear, and to what extent they are related. I suggest that V+that is probably a survivor from Old English and V+NP+that a later innovation. I also examine the factors likely to have contributed to the persistence of V+that in ME, and to the emergence of V+NP+that, such as language contact and the influence of other existing Middle English constructions which may have played a role in the spread of V+NP+that.
