When a person keeps repeating themselves or goes off on tangents during a conversation, they are said to be going "around in circles." However, there are several other synonyms that can be used to describe this behavior. One such term is "beating around the bush," which means to avoid getting to the point. Another synonym is "circular reasoning," which is when someone tries to prove their argument by using their argument as evidence. "Rehashing" is another word meaning to repeat or go over something again and again. Lastly, "spinning one's wheels" describes the act of putting in effort, but achieving no result. Using these synonyms can make conversations more interesting, and offer variety in language.
