Since 1995, head-movement has been something of a no-fly zone within Principles and Parameters theory. No solution has emerged that both captures the central properties of head-movement as understood from previous study and implements Chomsky’s proposal that it is ‘phonological’ in nature. In this paper, I observe that the Conflation mechanism proposed in Hale and Keyser 2002 has the right characteristics to be such a solution within more conventional MP assumptions, and apply it to the problem of synthetic compounds in English.
