This document discusses the faculty of language and how it generates hierarchical syntactic structures through recursive operations like Merge and movement. It describes: - The faculty of language narrow (FLN) which builds syntax through recursion and Merge, combining two items into one. - The faculty of language broad (FLN) which interfaces language with other cognitive systems through sensory-motor and conceptual-intentional interfaces. - Other syntactic operations like labeling, which provides labels to constituents, and movement, which moves constituents to other positions for licensing or non-syntactic reasons. - Three types of movement: head movement, argument movement, and non-argument movement.
