logical form or covert syntax is a syntactic level introduced in recent generative approaches. using the ideas of first-order predicate logic, it interprets the strings whose elements cannot move in s–structure, because an element moves if it does not acquire its necessary scope. but unlike the predicate logic, logical form is based on syntactic principles and rules. therefore, logical form is ...

this research is concerned with a concept called “um-ol-baab”, which has wide applications in syntax. this article attempts to clarify this concept and specify terms which are used to directly or indirectly refer to it. this has been done by examining the views and works of a good number of syntacticians. three subgroupings have been revealed :1) devices the structure of which are compatibl...

For analyzing the structure of a sentence we will use constituent analysis, a hierarchical model introduced by Chomsky [1]. In this framework, sentences are modeled in the form of a parse tree (see Figure 1), where leaves are lexical items, or terminals, and internal nodes are constituent labels. The constituent labels form grammatical types from the lexical items, and lexical items form the se...
