an interjection to lend emphasis― sometimes, a profanity― Figure of emphasis in which a single word or short phrase, usually interrupting normal speech, is used to lend emphasis to the words on either side of the expletive. Typical examples include: in fact, of course, to be sure, indeed, I suppose, I hope, , I think, you know, you see, clearly, in any event, in effect, certainly, remarkably. Example: "I would like, if I may, to take you on a strange journey." ― from the movie Rocky Horror Picture Show
