• "There are two kinds of disjuncts: style disjuncts and content disjuncts. Style disjuncts express comments by speakers on the style or manner in which they are speaking: frankly as in Frankly, you have no chance of winning (= I am telling you this frankly); personally in Personally, I'd have nothing to do with them; with respect in With respect, it is not up to you to decide; if I may say so in They are rather rude, if I may say so; because she told me so in She won't be there, because she told me so (= I know that because she told me so). Content disjuncts comment on the content of what is being said. The most common express degrees of certainty and doubt as to what is being said: perhaps in Perhaps you can help me; undoubtedly in Undoubtedly, she is the winner; obviously in Obviously, she has no wish to help us."
