In the context of *Deutsch als Fremdsprache* (DaF), the concept of error refers to deviations from the accepted norms of the German language in pronunciation, grammar, vocabulary, spelling, or communication. Errors are an inevitable and natural part of the language learning process because learners gradually construct their knowledge of the target language. Rather than viewing errors merely as signs of failure, modern language teaching considers them valuable indicators of learners' progress, developmental stage, and learning needs. Teachers analyze errors to identify areas requiring additional instruction and to adapt their teaching strategies accordingly. A distinction is often made between mistakes and errors. Mistakes are temporary lapses caused by factors such as fatigue, inattention, or nervousness, and learners can often recognize and correct them independently. Errors, however, result from incomplete or incorrect understanding of language rules and require systematic learning and practice for correction. Error analysis helps teachers understand the causes of these errors, which may arise from interference from the mother tongue, overgeneralization of grammatical rules, lack of vocabulary, or insufficient exposure to authentic language use.
