Error

While the word error has different precise meanings in different domains, it is always related to the lack of correlation between the intended consequences of an action and the actual consequences of that action. The concrete meaning of the Latin word error means "wandering" or "straying", although the metaphorical meaning "mistake, misapprehension" is actually more common. 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.
