Sentential Subject Constraint
SYNTAX: one of the constraints on movement proposed by Ross (1967). It states that
No element dominated by an S may be moved out of that S if that S is dominated by an NP which itself is immediately dominated by S,and is meant to capture the fact that categories cannot be moved out of a sentential subject. EXAMPLE: consider (i) and (ii), both containing a sentential subject (the for-clause and the that-clause respectively).
(i) [for Haarhuis to beat Becker] is easy (ii) [that Haarhuis beat Becker] pleased usThe Sentential Subject Constraint now correctly predicts that wh-movement of Becker out of the sentential subject leads to ungrammaticality:
(i') * Who is [for Haarhuis to beat t] easy? (ii') * Who did [that Haarhuis beat t] please us?The Sentential Subject Constraint falls under the Subject Condition of Huang's (1982) Condition on Extraction Domain.
