Syntactic relations and syntactic constraints

This chapter continues the discussion of the formal architecture of LFG and of ways to describe and constrain constituent structures and functional structures. The chapter introduces additional relations and constraints on structures, and discusses concepts fundamental to our formal theory, including regular expressions (Section 6.1); sets (Section 6.3); off-path constraints (Section 6.6); templates (Section 6.7); relations between f-structures such as f-command, subsumption, and restriction (Section 6.9); c-structure/f-structure constraints including empty nod rules (Section 6.10); and precedence relations (Section 6.11). For most readers, this chapter best serves as a reference to be consulted for definition and discussion of concepts and relations that are used in the analyses presented in the remainder of the book.
