The noun "Orient" means east. The intranstive verb "orient" means to face east. The transitive verb "orient" means to situate something such that it faces east or is alligned to the east. Something so arranged has an east-west "orientation" as a result of the action of the person doing the situating or alligning. From the quite legitimate work "orientation" derives the beast barbarism "orientate." While it cannot be said that "there is no such word," it can be said that persons who use this word (1) are ill-informed, (2) need correction and (3), if resistent to correction, ought be boiled in their own suet. And, of course, they need our prayers.
