拓展：語(yǔ)法特征
抽象性
語(yǔ)法是從眾多的語(yǔ)法單位里抽象出其中共同的組合方式、類型及如何表達(dá)語(yǔ)義的規(guī)則。“語(yǔ)法從詞和句的個(gè)別和具體的東西中抽象出來(lái)，把作為詞的變化和用詞造句的基礎(chǔ)一般的東西拿來(lái)，并且以此構(gòu)成語(yǔ)法規(guī)則、語(yǔ)法規(guī)律�！崩鐫h語(yǔ)里有“看看、說(shuō)說(shuō)、寫(xiě)寫(xiě)、學(xué)習(xí)學(xué)習(xí)、討論討論”這一詞的重疊現(xiàn)象，這反映出一條詞的變化規(guī)律：有些動(dòng)詞可以用重疊的方法來(lái)表示動(dòng)作的某一語(yǔ)義類型，即表示少量或短時(shí)。又如漢語(yǔ)里有“心情舒暢。/服裝整齊。/步調(diào)一致。/前途光明�！边@些句子，他們意思各異，但結(jié)構(gòu)相同，都是名詞在前，形容詞在后，直接組合，表示被陳述和陳述的關(guān)系，加上句調(diào)就構(gòu)成了主謂句。由此可見(jiàn)，語(yǔ)法指的是抽象出來(lái)的公式，舍棄了個(gè)別的、具體的內(nèi)容，一種語(yǔ)言里的詞多如牛毛，由這些詞組合而成的具體短語(yǔ)和句子更是難以計(jì)數(shù)，但是它內(nèi)部的組合規(guī)則和格式是很有限的。語(yǔ)法學(xué)的任務(wù)是描寫(xiě)，解釋組成詞、短語(yǔ)和句子的規(guī)則和格式。由此可見(jiàn)，語(yǔ)法具有抽象性、概括性。
生成性
我們可以根據(jù)有限的語(yǔ)法規(guī)則造出無(wú)數(shù)合格的句子來(lái)，這就表現(xiàn)了語(yǔ)法的生成性。語(yǔ)法規(guī)則的生成性，集中的表現(xiàn)在兩個(gè)方面：組合關(guān)系和聚合關(guān)系。
層次性
語(yǔ)法從表面上看是線性排列的東西，但是語(yǔ)法結(jié)構(gòu)卻是有層次性的。除了聯(lián)合短語(yǔ)外，主謂，述賓，述補(bǔ)，偏正等短語(yǔ)都能切分出兩個(gè)直接成分。直接成分還可以進(jìn)一步切分出更小的直接成分，這樣復(fù)雜短語(yǔ)就可以由大到小分析出若干層次。例如漢語(yǔ)：我們進(jìn)行社會(huì)調(diào)查
|__||_____________|主謂關(guān)系
|__||________|述賓關(guān)系
|___||___|偏正關(guān)系
語(yǔ)法的層次性與語(yǔ)法的遞歸性密切相關(guān)。
系統(tǒng)性
語(yǔ)法是一個(gè)嚴(yán)密的立體的開(kāi)放的系統(tǒng)網(wǎng)絡(luò)。所謂“嚴(yán)密”，是指系統(tǒng)的內(nèi)部是相互制約的，要受到一定的規(guī)則的支配，不是可以隨心所欲的。所謂“立體”，是指語(yǔ)法系統(tǒng)包括了句法結(jié)構(gòu)，語(yǔ)法意義，語(yǔ)言運(yùn)用這三個(gè)交叉的不同平面。所謂“開(kāi)放”，是指語(yǔ)法系統(tǒng)是發(fā)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(chǎn)生。語(yǔ)法系統(tǒng)內(nèi)部又由若干個(gè)子系統(tǒng)構(gòu)成，例如語(yǔ)素系統(tǒng)，詞類系統(tǒng)，短語(yǔ)系統(tǒng)，句子系統(tǒng)，句群系統(tǒng)，每個(gè)子系統(tǒng)可能由若干個(gè)孫系統(tǒng)構(gòu)成。詞類系統(tǒng)內(nèi)部可以分為實(shí)詞系統(tǒng)和虛詞系統(tǒng)。句子系統(tǒng)內(nèi)部可以分為單句系統(tǒng)，復(fù)句系統(tǒng)等等，從而形成一個(gè)系統(tǒng)網(wǎng)絡(luò)。
遞歸性
遞歸是說(shuō)，各種語(yǔ)法結(jié)構(gòu)的關(guān)系是有限的，但是在語(yǔ)言單位的組合過(guò)程中，可以反復(fù)無(wú)限地使用這些有限的規(guī)則，從而使句法結(jié)構(gòu)復(fù)雜化。例如：我買書(shū)。/我買一本書(shū)。/我買一本有趣的書(shū)。/我買一本××寫(xiě)的有趣的書(shū)。
如果沒(méi)有這種“遞歸性”，某種語(yǔ)法規(guī)則在一個(gè)句法結(jié)構(gòu)里使用過(guò)一次就不能再用了。那么，我們能夠造出的句子一定是相當(dāng)簡(jiǎn)單而缺乏變化的，一定不能靈活自如的表達(dá)各種復(fù)雜的思想感情。
穩(wěn)固性
語(yǔ)法與基本詞匯構(gòu)成語(yǔ)言的基礎(chǔ)，具有很大的穩(wěn)固性。語(yǔ)法也會(huì)隨著時(shí)間的推移而發(fā)展演變，但是語(yǔ)法的變化比詞匯，語(yǔ)音的變化緩慢得多，而且語(yǔ)法很難受到外來(lái)因素的影響而改變。語(yǔ)法的穩(wěn)固性與語(yǔ)法的抽象性密切相關(guān)。語(yǔ)法是一個(gè)由各種抽象規(guī)則構(gòu)成的有機(jī)系統(tǒng)，許多語(yǔ)法手段和語(yǔ)法范疇歷經(jīng)千百年而很少發(fā)生變化。
民族性
每種語(yǔ)言都有明顯的民族特點(diǎn)。不僅表現(xiàn)在語(yǔ)音和詞匯上，也表現(xiàn)在語(yǔ)法上。漢語(yǔ)的語(yǔ)法比較隱蔽，漢語(yǔ)語(yǔ)法的民族性特點(diǎn)是在同其他語(yǔ)言的比較中得出的。漢語(yǔ)語(yǔ)法中語(yǔ)序和虛詞的運(yùn)用非常重要。印歐語(yǔ)常用詞尾的形態(tài)變化來(lái)表示句法功能的變化。比較：
漢語(yǔ)是SVO型語(yǔ)言：陳述句一般順序是：主語(yǔ)+動(dòng)詞+賓語(yǔ)。
日語(yǔ)是SOV型語(yǔ)言：陳述句的順序是：主語(yǔ)+賓語(yǔ)+動(dòng)詞。
英語(yǔ)：由于沒(méi)有量詞，數(shù)詞可以直接和名詞組合。如：a table(桌子)/a pen(鋼筆)。漢語(yǔ)口語(yǔ)數(shù)詞一般不能直接與名詞組合，中間要用量詞來(lái)組接，并且哪個(gè)名詞與哪個(gè)量詞組合有一定的搭配習(xí)慣。如：一張桌子……，但文言文中數(shù)詞可與名詞組合(因?yàn)槲难晕漠a(chǎn)生時(shí)，漢語(yǔ)里還沒(méi)有量詞)，如“一桌一椅一扇一撫尺而已”，“一草一木”。世界上有許多語(yǔ)言，詞語(yǔ)的排列順序是比較自由的。如在俄語(yǔ)中，“我愛(ài)祖國(guó)”便有三種語(yǔ)序，漢語(yǔ)卻是另外一種情形，語(yǔ)序非常重要。
