Error!

The word error has different meanings and usages relative to how it is conceptually applied. The concrete meaning of the Latin word error is "wandering" or "straying". To the contrary of an illusion, an error or a mistake can sometimes be dispelled through knowledge (knowing that one is looking at a mirage and not at real water doesn't make the mirage disappear). However, some errors can occur even when individuals have the required knowledge to perform a task correctly. Examples include forgetting to collect your change after buying chocolate from a vending machine, forgetting the original document after making photocopies, and forgetting to turn the gas off after cooking a meal. These slip errors can occur when an individual is distracted by something else.
