The phrasal verb "yak on" is predominantly used in informal speech and is commonly employed to describe someone talking persistently, usually at length and often about trivial or uninteresting topics. It carries a slightly negative connotation, implying not only that the speaker is long-winded but also that the content of the conversation might lack substance. It is frequently used in contexts where the speaker wants to express mild annoyance or impatience with someone who is talking too much or needlessly dwelling on a subject. The usage of "yak on" in formal writing or speech is rare due to its colloquial tone, making it more suitable for casual conversations or informal written communications, such as blogs or emails.
