拓展：語法特徵
抽象性
語法是從衆多的語法單位裏抽象出其中共同的組合方式、類型及如何表達語義的規則。“語法從詞和句的個別和具體的東西中抽象出來，把作爲詞的變化和用詞造句的基礎一般的東西拿來，並且以此構成語法規則、語法規律。”例如漢語裏有“看看、說說、寫寫、學習學習、討論討論”這一詞的重疊現象，這反映出一條詞的變化規律：有些動詞可以用重疊的方法來表示動作的某一語義類型，即表示少量或短時。又如漢語裏有“心情舒暢。/服裝整齊。/步調一致。/前途光明。”這些句子，他們意思各異，但結構相同，都是名詞在前，形容詞在後，直接組合，表示被陳述和陳述的關係，加上句調就構成了主謂句。由此可見，語法指的是抽象出來的公式，捨棄了個別的、具體的內容，一種語言裏的詞多如牛毛，由這些詞組合而成的具體短語和句子更是難以計數，但是它內部的組合規則和格式是很有限的。語法學的.任務是描寫，解釋組成詞、短語和句子的規則和格式。由此可見，語法具有抽象性、概括性。
生成性
我們可以根據有限的語法規則造出無數合格的句子來，這就表現了語法的生成性。語法規則的生成性，集中的表現在兩個方面：組合關係和聚合關係。
層次性
語法從表面上看是線性排列的東西，但是語法結構卻是有層次性的。除了聯合短語外，主謂，述賓，述補，偏正等短語都能切分出兩個直接成分。直接成分還可以進一步切分出更小的直接成分，這樣複雜短語就可以由大到小分析出若干層次。例如漢語：我們進行社會調查
|__||_____________|主謂關係
|__||________|述賓關係
|___||___|偏正關係
語法的層次性與語法的遞歸性密切相關。
系統性
語法是一個嚴密的立體的開放的系統網絡。所謂“嚴密”，是指系統的內部是相互制約的，要受到一定的規則的支配，不是可以隨心所欲的。所謂“立體”，是指語法系統包括了句法結構，語法意義，語言運用這三個交叉的不同平面。所謂“開放”，是指語法系統是發展變化的，一直在不斷地自我完善，舊的成份被逐漸淘汰，新的因素在不斷產生。語法系統內部又由若干個子系統構成，例如語素系統，詞類系統，短語系統，句子系統，句羣系統，每個子系統可能由若干個孫系統構成。詞類系統內部可以分爲實詞系統和虛詞系統。句子系統內部可以分爲單句系統，複句系統等等，從而形成一個系統網絡。
遞歸性
遞歸是說，各種語法結構的關係是有限的，但是在語言單位的組合過程中，可以反覆無限地使用這些有限的規則，從而使句法結構複雜化。例如：我買書。/我買一本書。/我買一本有趣的書。/我買一本××寫的有趣的書。
如果沒有這種“遞歸性”，某種語法規則在一個句法結構裏使用過一次就不能再用了。那麼，我們能夠造出的句子一定是相當簡單而缺乏變化的，一定不能靈活自如的表達各種複雜的思想感情。
穩固性
語法與基本詞彙構成語言的基礎，具有很大的穩固性。語法也會隨着時間的推移而發展演變，但是語法的變化比詞彙，語音的變化緩慢得多，而且語法很難受到外來因素的影響而改變。語法的穩固性與語法的抽象性密切相關。語法是一個由各種抽象規則構成的有機系統，許多語法手段和語法範疇歷經千百年而很少發生變化。
民族性
每種語言都有明顯的民族特點。不僅表現在語音和詞彙上，也表現在語法上。漢語的語法比較隱蔽，漢語語法的民族性特點是在同其他語言的比較中得出的。漢語語法中語序和虛詞的運用非常重要。印歐語常用詞尾的形態變化來表示句法功能的變化。比較：
漢語是SVO型語言：陳述句一般順序是：主語+動詞+賓語。
日語是SOV型語言：陳述句的順序是：主語+賓語+動詞。
