When trying to convey the idea that something is undeniably true, there are many alternative phrases that can be used instead of "ringed true." Examples include "rung true," "struck a chord," "hit home," "resonated," "was on the mark," "hit the nail on the head," and "was spot on." These phrases all convey a sense of certainty and accuracy, indicating that the stated idea is not merely plausible or likely, but absolutely true. No matter which phrase is used, the intention is the same: to communicate the idea that the statement in question is accurate and cannot be disputed.
