Syntax
Types of movement: A summary
Note that there are certain restrictions on movement. For example, heads can only move to head-positions (e.g. INFL-to-COMP movement, Verb-to-INFL movement). This type of movement is called head movement (or head-to-head movement).
Phrasal constituents (i.e. complete XPs) can only move to phrasal positions. A typical position that can serve as a "landing site" for moved phrasal constituents is the specifier position. In the previous sections we have introduced two types of movement that affects phrasal constituents.
For more details on movement in questions and for other types of movement (e.g. passive, raising) please refer to the module Syntactic Theory.
