语际语
语际语inter-language
SLA is viewed as a process of creative construction, in which a learner constructs a series of internal representations that comprises the learner’s interim knowledge of the target language, known as inter-language, that is, the language that a learner constructs at a given stage of SLA.
第二语言习得是一个创造性构建过程，在这一过程中，学习者构建了一系列内在的表达方式，这种表达方式组成了学习者对目的语的过渡性知识，此种知识被称为语际语，即学习者在第二语言习得的某一阶段所说的语言。
Specifically, inter-language consists of a series of interlocking and approximate linguistic systems in-between and yet distinct form the learner’s native and target language. It represents the learner’s transitional competence moving along a learning continuum stretching from one’s L1 competence to the target competence.
具体地说，语际语包含一系列与本族语和目的语相关并相似的语言体系。既介于它们之间，又不同于它们的语言体系。它反映了学习者从第一语言能力向目的语语言能力的过度。
Learner’s inter-language fossilized some way short of target language competence while the internalized rule system contained rules that are different from those of the target language system. The fossilization of the learner’s inter-language is believed to be a major source of incorrect forms resistant to further instruction.
学习者的语际语在未到达目的语言能力时，就发生了僵化，此时其内在化的规则体系与目的语语言体系所包含的规则不尽相同。据认为，学习者语际语的僵化现象是导致错误的语言形式的不可救药的主要原因。
