      Root

      1)詞根

      2)舌根

      3)根節點;根句

       

      (1) A term often used in linguistics (and traditionally used in historical linguistics) as part of a classification of the kinds of element operating within the structure of a word. A root is the base form of a word which cannot be further analyzed without total loss of identity. Putting this another way, it is that part of the word left when all the affixes are removed. From another point of view, roots are sometimes classified as ‘simple’ or ‘complex’/ ‘compound’, though for the latter the term stem is commonly used. From a semantic point of view, the root generally carries the main component of meaning in a word. From a historical viewpoint, the root is the earliest form of a word, though this information is not relevant to a synchronic analysis.

      (2) The furthest-back part of the tongue, opposite the pharyngeal wall, not normally involved in the production of speech sounds; also called the radix. It is, however, involved in advanced tongue root articulation - a movement which expands the front-back diameter of the pharynx, used phonologically in some languages as a factor in contrasts of vowel harmony.

      (3) In generative grammar, the term is sometimes used to refer to the topmost node in a tree diagram. In non-linear phonology, the root node is the one which dominates all other features in the hierarchy. In transformational grammar it also refers to a type of transformation which applies only to full sentence structure and not to embedded sentences.

       

      (1)語言學常用術語(傳統上用于歷史語言學),指詞結構的一類成分。詞根是詞的基礎形式,不能再作進一步分析,不然就完全失去其個性。換句話說,詞根是將詞內的詞綴都拿掉后剩下的部分。從另一個角度,詞根有“簡單”和“復雜/復合”之分,前者不可再分析成若干組成語素,后者是幾個簡單詞根的某種組合,不過常用詞干稱之。從語義的角度看,詞根一般負載詞的主要意義部分。從歷史角度看,詞根是詞的最早形式,雖然這一信息與共時分析的結果相一致。

      (2)舌最靠后的部位,對著咽腔壁,通常不用于語音的產生;也稱作radix。但是提前的舌根發音動作要涉及舌根,這個動作擴展咽的前后直徑,在有些語言中是元音和諧對立的一個區別性因素。

      (3)生成語法有時用來指樹形圖中的頂端節點。在非線性音系學中,根節點是層級中統制所有其他特征的一個節點。在轉換語法中,也指一類只適用于完整句子結構不適用于嵌套句的轉換。
