About This Root

From Latin errāre, 'to wander, lose one's way.' Romans saw a mistake as literally straying off the correct path, so the physical idea of wandering became the moral idea of being wrong: error, err, erroneous. The wandering image survives most clearly in erratic ('moving unpredictably') and aberration ('a straying away from normal').
