Accepted Answer

Containing a mistake; not true or accurate. Fallacious is a formal and intellectual word. We rarely use it in casual speech; when we do, we risk sounding a bit full of ourselves and all-knowing. But it's used widely in writing, especially when one writer is arguing with another. And it's used to describe both errors in fact and errors in reasoning, including fallacies of the kind described in the previous entry.
