Head-movement has played a central role in morpho-syntactic theory, but its nature has remained unclear. While it is widely accepted that the main grammatical constraint controlling head-movement is the Head Movement Constraint (HMC), this constraint is flouted in many of the linguistic structures examined in this book. More specifically, the strictures of the HMC turn out to be sometimes inactive for specific grammars allowing multiple head-movement to take place in particular syntactic contexts. In The Grammar of Multiple Head-Movement, Phil Branigan shows that multiple head-movement is...
