errore

Errore is the Italian noun meaning "error" or "mistake." In everyday language it denotes a deviation from truth, correctness, or intent, such as a miscalculation, a slip of the tongue, or a faulty action. In technical contexts it refers to observed deviations between measured or computed values and their true or expected ones. The term derives from Latin errare, "to wander," through Old Italian.

Common usages include human error (mistakes due to cognition, fatigue, or misperception), measurement error (random or systematic deviations affecting accuracy and precision), computational error (bugs, exceptions, or hardware faults causing incorrect results), and linguistic error (slips in speech or writing).

In science and engineering, error analysis and calibration identify, quantify, and reduce errors. Systematic errors bias results, while random errors diminish with repeated measurements. Uncertainty quantification expresses the confidence in measurements and models.

In law and philosophy, errore can denote judicial or epistemic mistakes, such as errore giudiziario (wrongful conviction) or errore di fatto or errore di diritto in judgments.

Some errors are considered unavoidable within a given tolerance, while others result from negligence or malpractice.
