The word "erroneous" traces back to the Latin errōneus, meaning "wandering" or "straying," which itself comes from errare ("to wander or err"). Over time, the sense of physical wandering evolved metaphorically to describe intellectual or factual deviation—hence its modern meaning of "incorrect." The suffix -oneous reinforces the adjectival form, emphasizing the state of being in error.
