The phrase "as they say" is commonly used to introduce quotes, idioms, and popular sayings into conversations or written works. However, there are other ways to convey a similar meaning without using this overused expression. For example, "as the saying goes," "so the story goes," "according to popular belief," "as the old adage states," and "as tradition dictates." These alternatives not only add variety to the language but also demonstrate a deeper understanding of the idea being conveyed. It's essential to remember that the overuse of any phrase can distract from the content's message, so choose wisely with what phrase to use.
