Obligatory Transformation

强制性转换

 

In early transformational grammar, the term refers to one of the two types of transformational rule postulated by Noam Chomsky in his book Syntactic Structures (1957), the other being optional. An obligatory transformation is one which must apply at a given stage in a derivation, when its structural description is met, if a well-formed sentence is to result, e.g. the rule which attaches affixes to their base forms.

 

诺姆·乔姆斯基在其《句法结构》(1957)一书中假设的两类转换规则之一,另一类是非强制性转换。强制性转换是指:如要得出合式的句子,在派生过程的某一阶段只要符合其结构描写就必须进行的转换;例如将词缀附加于基础形式的转换规则。
