When we want to express that something has been proven or supported by evidence or facts, we can use the phrase "borne out." However, there are a variety of synonyms that can be used to convey the same meaning. For example, we could say that something has been validated, substantiated, verified, or confirmed. We could also use the words proven, established, demonstrated, or evidenced. In some situations, we might say that something has been supported or upheld, indicating that it has been shown to be true or accurate. Regardless of the specific word choice, the goal is to convey the idea that something has been shown to be factual or valid.
