- Disambiguation: For Teflpedia's errors see Teflpedia:Errors
An error is a use of language that does not conform to expected norms. This definition is dependent on two factors; (1) deciding on what language norms are, and (2) deciding which degree of conformity to those norms is.
Language learners make frequent errors as they practice. Modern language teaching methodology recognises this and allow for it, though older methodologies were heavily focused on error reduction/error avoidance. Language learners often develop stabilised errors and fossilised errors.
Error analysis can identify what the error is and why the learner made it.
Errors may be subject to error correction.
