Island

SYNTAX: domain which does not allow extraction. Most of the islands distinguished today were first described in Ross (1967). EXAMPLE: Well-known examples are wh-islands, Complex NP's and coordinate structures. The restrictions on extractability (Island conditions) are often designated as the Wh-island Condition, the Complex NP Constraint (CNPC), and the Coordinate Structure Constraint (CSC), respectively. See Bounding theory.
