      Terminal

      終端

       

      A term used in generative linguistics to identify certain characteristics of the output of the syntactic component of the grammar. A terminal element or terminal symbol refers to the units employed in the syntactic representation of a sentence, after all the rules have been applied, viz. the morphemes, formatives, features, such as the, -en, +, #, man. Terminal symbols are distinguished from non-terminal (or ‘auxiliary’) elements, which are used in formulating rules. The former are usually written in lower-case letters, the latter in upper-case (e.g. NP, VP). A node which does not dominate other categories is a terminal node. A string consisting of terminal elements is known as a terminal string, i.e. the final string generated by a phrase-structure grammar.

       

      生成語言學術語,用來指語法的句法部分的輸出的某些特點。終端成分或終端符號指所有規則都應用后句子的句法表征式所采用的單位,即語素、構形成分、特征等,如the(定冠詞),-en(后綴),+,#,man“男人”。終端符號區別于非終端或“輔助”成分,后者用于規則的闡述。前者一般用小寫字母表示,后者一般用大寫字母(如NP,VP)。不統制其他語類的節點是終端節點。由終端成分組成的語符列稱作終端語符列,即短語結構語法生成的最終語符列。
