When you want to express that you have heard something from someone else, there are a variety of phrases to use instead of the standard "rumor/word/legend has it that." For example, you could say "it's been said that," "apparently," "I heard through the grapevine," "according to sources," or "word on the street is." These phrases all suggest that the information has been passed along informally and may not be completely verified. Choosing a different phrase can add variety to your writing and help you to express your ideas more effectively. It also allows you to highlight the informal nature of the information you are sharing.
