Recursive modes of appositive clause structures in English
This paper explores the ways in which complex appositive clause structures in English are constructed and the differences and commonalities between these ways.Through counting and analyzing the appositive clauses in an academic English book Grammaticalizaiton(Hopper &Traugott 2001),we find that complex appositive clause structures are generated by two recursive modes-marginal component recursion and core component recursion,whose rewriting rules are different.The multiple applications of marginal component recursion,namely multiple recursions,can generate multiply recursive structures.Core component recursions are more generative than multiple recursions.However,they show some commonalities;that is,they both have the property of rightward iteration,thus making recursive computation easier.
