bounding theory

**SYNTAX: **Theory about the locality of movement. The main principle of Bounding theory is the Subjacency condition, which forbids movement across more than one
**bounding node**.
** EXAMPLE:** in (i) *which books* has been moved over two bounding nodes, NP and CP. In (ii), NP and IP are the relevant bounding nodes. In (i) the so-called
**Complex NP Constraint** is violated, in
(ii) the so-called **Subject Condition**. Thus,
the Subjacency condition subsumes both the Complex NP Constraint and the Subject Condition.

(i) *which book_{i }did John meet [_{NP}a child [_{CP}who read t_{i }]] (ii) *the man [_{CP}who_{i }[_{IP}[_{NP}pictures of t_{i }] are on the table]]
