言談與語法是功能學派語言學的一支，主張語言內部結構會受言談層次的因素影響。一般言談中所使用的語言形式會受到認知及交際因素的鼓勵或牽制，而語法就是日常言談中那些一再被重複使用的語言形式而已。本文討論一些言談與語法學者所探出的觀念，回顧最此學說的理念處理漢語的一些研究，並簡略提出幾條未來研究的可行路線。

　　　　　Discourse-and-grammar is a branch of functional linguistics that takes the position that the internal structures can be shaped by forces arising out of discourse. Cognitive and communicative factors motivate and/or constrain the way speech patterns are used in verbal interaction. Grammar is but a set of entrenched speech patterns due to frequents use in daily talk. This paper discusses that main concepts proposed by scholars working in iscourse-and-grammar, surveys recent studies of Chinese that lake this approach, and briefly mentions a number of promising directions for future research.
