1 DISCONTINUOUS CONSTITUENCY IN SEGMENT GRAMMAR

Segment Grammar (SG) is a grammar formalism which is especially suited to model the incremental generation of sentences. SG is characterized by a dual level of syntactic description: f-structures, which are unordered functional structures composed out of syntactic segments, and c-structures, which represent left-to-right order of constituents. True discontinuities in SG are viewed as differences between immediate dominance (ID) relations in c-structures and those in corresponding f-structures. Constructions which are treated in this way include clause union, right dislocation, and fronting. Separable parts of words such as verbs and compound prepositions are not viewed as true discontinuities but as lexical entries consisting of separate syntactic segments
