the contrast in jeeves's and bertie's diction leads to what wodehouse scholar kristin thompson terms the "translation device". jeeves often says something that bertie repeats in less formal language, either to make sure he understands or to translate for someone else. this device is used for comic effect in "the aunt and the sluggard", when jeeves provides a long, formal, sophisticated description of his plan for rocky to have someone else write letters about new york to his aunt. when rocky is confused by jeeves's complex speech, bertie translates jeeves's idea for rocky in much fewer, simpler words. the humour in these situations arises from the fact that bertie's version is much shorter than jeeves's.
