Using the pragmatically-grounded theoretical frameworks of Construction Grammar and the Multiple Grammar Model, this special issue attempts to demonstrate that a speaker's grammatical knowledge is not monolithic, but is multifaceted. Through illustrations of specific constructions including those perceived as the “periphery” of a grammar, the six papers emphasize the importance of acknowledging grammatical variability, interconnectedness of constructions used in a variety of genres and modes, and real speakers' communicative competence to support such a diverse system. That speakers can call up select grammatical constructions depending on the specific situation shows that speakers' organization of grammar involves the pragmatic information about language use in context, supported by the speakers' experiences with actual usage. Some constructions are conventionalized and strongly tied to the mode or genre, while others are flexibly chosen for their function. This grammatical multiplicity is described as a cognitive system within individual speakers and as a set of social practices.

本期特刊利用以语用为基础的构式语法和多重语法模型的理论框架，试图证明说话者的语法知识不是单一的，而是多方面的。通过对包括那些被视为语法“外围”的特定构式的说明，六篇论文强调了承认语法可变性、用于各种体裁和模式的构式的相互联系以及真实说话者的交际能力以支持这种语法的重要性。多样的系统。说话人可以根据具体情况调用选定的语法结构，这表明说话人的语法组织涉及语境中语言使用的语用信息，并得到说话人实际使用经验的支持。一些结构是常规化的，并且与模式或流派密切相关，而另一些结构则是根据其功能灵活选择的。这种语法多样性被描述为个体说话者内部的认知系统和一组社会实践。
