Head Movement Constraint
SYNTAX: a constraint originally formulated in Travis (1984:131):
(i) An X0 may only move into the Y0 which properly governs itThe HMC basically places a limit on the distance over which a head may be moved (head movement). In effect, the HMC prohibits skipping a governing head position, as in (ii): buy moves to COMP in disregard of its being properly governed only by the I0 will.
(ii) * [CP What [C buyi] [IP John [I will] [VP ti]]]?Recently, it has been argued that the HMC can be derived from more general principles, such as the ECP.
