Abstract:

In the process of foreign language acquisition,the quality of a learner’s writing ability is closely linked to their vocabulary repertoire and its application.This study focuses on Chinese-English-German trilingual learners,integrating theories of third language acquisition(TLA)and error analysis to investigate negative transfer phenomena from the first language(Chinese)and second language(English)during the acquisition of a third language(German).Employing a corpus-based approach,the research systematically identifies and categorizes lexical errors,with an emphasis on analyzing negative transfer patterns at the conceptual level of vocabulary.The findings aim to provide practical pedagogical recommendations for German language instruction.

Key words: third language acquisition(TLA), corpus, lexical error analysis, language transfer, foreign language teaching methodology
