Hi Jorge! First of all, don't ever apologize for making mistakes when you are learning a language! Making mistakes is part of the process, and the only people who expect you to be perfect are those who are not worth your time. (Also, let's not forget that even native speakers make mistakes routinely!) Now, to your question: this use of "have/has it" is generally spoken-only. It's rare to see it written in any formal documents (unless quoting a person who said it). It does mean what you think it means: the same as "there is a ____ that..." In other words, "Rumor has it he was drunk" = "There is a rumor that he was drunk." I hope I've helped answer your question. Please let me know if I haven't.

Hi Jorge, You have asked a very interesting question. I share with students in my class that very often, the most commonly used words or grammar items may be the ones we least understand. Do not be too conscious that you are asking because it means you are open to learning. "have it" is used commonly in questions. Example: Do the boys have it? Does Judy have it? "has it" means something that is generally thought to be true although not official or known to be a fact. So we use it to describe a rumour often. Example: Rumour has it that Emily is migrating. (Perhaps it is true. Someone saw Emily signing the application form. Did she submit them after all? No one knows for sure.) We do not write "The rumour says that......" as "rumour" is clearly not a person speaking. When we use "have to" / "has to" / "had to", we usually refer to a duty or obligation. Example: John has to finish his homework. The pedestrians have to observe traffic rules. They had to postpone their trip due to poor weather. I hope I have placed the different uses into clearer categories for you. Keep asking. Cheers, Lance
