ABSTRACT
This conclusion presents some closing thoughts on key concepts discussed in the preceding chapters of this book. The book brought together some of the main elements of Syntactic Theory and summarizes the main features of Principles and Parameters (P&P) including the minimalist version of the framework and the main features of Head-driven Phrase Structure Grammar (HPSG). It elaborates the main differences and similarities between these two frameworks with some closing comments on the future of syntactic theory. Syntactic theory has its origins in Noam Chomsky's 1957 book Syntactic Structures. It can be said to have two goals. On the one hand, it is concerned to develop precise descriptions of aspects of the syntax of various languages. On the other hand, it aims to develop a general theory of syntax, specifying what languages have in common in this area and how they can vary. This is often known as a theory of universal grammar.
