{{main|Error (linguistics)}}

In [[applied linguistics]], an error is an unintended deviation from the immanent rules of a [[variety (linguistics)|language variety]] made by a [[second language]] learner. Such errors result from the learner's lack of knowledge of the correct rules of the target language variety.<ref>{{cite book |last= Ellis |first= Rod |author-link=Rod Ellis |title=The Study of Second Language Acquisition |url=https://books.google.com/books?id=3KglibyrZ5sC&pg=PA700 |year=1994 |publisher=[[Oxford University Press]] |location=[[Oxford]] |isbn= 0-19-437189-1 |page=700}}</ref> A significant distinction is generally made between ''errors'' (systematic deviations) and ''mistakes'' ([[speech error|speech performance errors]]) which are not treated the same from a linguistic viewpoint. The study of learners' errors has been the main area of investigation by linguists in the history of [[second-language acquisition]] research.{{sfn|Ellis|1994|p=43}}
