      Underlying

      底層的

       

      A term used in linguistics to refer to an abstract level of representation of a sentence postulated in order to explain the patterns encountered in the empirical data of a language. The notion of underlying representation or underlying forms is central to generative grammar, where a stage of underlying structure is recognized in the derivation of sentences. In early transformational grammar, the underlying phrase-marker refers to the structural description of a sentence which is the result of the phrase-structure rules; this underlying string then acts as the input to the transformational rules, which thereby produce ‘derived’ phrase-markers. Later, the term deep structure came to be used as a specific conception of underlying structure, in the context of Aspects of the Theory of Syntax, from which surface structures are transformationally derived. In government-binding theory, the term D-structure is used. The extent to which the various underlying representations of sentences have psychological reality has been and remains controversial.

       

      語言學用此術語指為解釋一種語言的經驗數據中存在的型式而假設的一個抽象的句子表征層面。底層形式是生成語法的一個中心概念,即在句子的派生過程中分出一個底層結構階段。早期的轉換語法中,底層短語標記指一個句子的結構描寫,是應用短語結構規則的結果;這個底層語符列然后充作轉換規則的輸入,從而產生“派生的”短語標記。后來,在《句法理論要略》的框架內,術語深層結構被用來專指底層結構,表層結構則通過轉換由此派生而成。管轄與約束理論轉而采用D-結構一語。句子的各種底層表征式在多大程度上具有心理的現實性,這一直是一個有爭議的問題。
