Generally, syntax is the main core of syntactocentric conception and the pragmatics and semantics (information structure) are considered to be the derivatives of syntax. On the other hand, the parallel architecture theory of the place of information structure in grammar structure contrasts the arguments of syntacto-centric conception by suggesting that there is no dominant component but a series of interacting components and the interactions are not necessarily mediated through the syntactic components.
However, although the theory of Syntactocentric architecture is largely premised on the belief that information structure including the relations between meaning and sound often arises from the mapping of various syntactic structures into phonetic form, recent theoretical developments have revealed that phonological structures have their limitations and their combinations cannot be merely reduced to syntactic terms. As a result, parallel architecture currently seems to be the most appropriate theory that can be used to explain the Place of information structure in grammar structure. One of the most commonly used parallel architecture approaches known as the role reference grammar (RRG) particularly posits that one single synactic representation of a sentence normally corresponds to the actual structure of a sentence.
