Since the language which the learner produces using these processes differs from both the mother tongue and the target language , it is sometimes called an interlanguage , or is said to result from the learner 's interlanguage system or approximative system .

学习者由这些过程产生的语言不同于母语和目的语，因而有时称为语际语，据说这是学习者语际体系或近似体系的结果。
