Mary, Why do you need the category "objective complement"? One of the problems of pedagogical grammar is that the grammarians and teachers make it too complicated by introducing unneeded terms. Note, by the way, your use of the passive: "Isn't this construction called...." The questions are "called by whom?" and "for what reason"? >>> Mary Tyler Knowles <[log in to unmask]> 05/22/95 05:17am >>> Subject: Re: Sentence Diagramming ---------------------------------------------------------------------- >In "He caused her to do it" you have an infinitive phrase with its own >subject (her). The phrase is the direct object of "caused." Ian't this construction called the "objective complement"? Mary Tyler Knowles ([log in to unmask]) The Winsor School. Boston, MA "I read; therefore, I am."
