Wrong or incorrect; based on false information or faulty reasoning. Containing or characterized by error or mistake.
From Latin 'erroneus' meaning 'wandering' or 'straying,' derived from 'errare' (to wander, err). The concept evolved from the idea of wandering off the correct path to making mistakes or holding incorrect beliefs.
Think of 'ERROR-neous' - it's literally full of errors! The root 'err' means to wander off the right path, like when you get lost and wander in the wrong direction. An erroneous belief is one that has wandered away from the truth.
