Like many other theories developed within the framework of HPSG, what is now called Linearization Theory started out as a refinement of theories that had been developed in the context of other theoretical frameworks. Specifically, the original form of Linearization Theory (see Reape (1994)) can be regarded as an interesting reformulation of ideas put forth within transformational grammar (McCawley (1982)), GPSG (Zwicky (1986)), and categorial grammar (Dowty (1996)). In recent years, however, the theory has evolved in an unexpected direction. In this paper, I will attempt to describe the novel, and in my opinion quite compelling perspective that the theory now offers in regard to extraposition, right-node raising (RNR), and the syntax-phonology-semantics interface.
