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 booki did John meet [NP a child 
       [CP who read ti ]]
(ii)  *the man [CP whoi [IP [NP pictures of ti ] 
       are on the table]]
