MORPHOLOGY: a notion proposed in DiSciullo & Williams (1987) which replaces Williams' (1981a) notion of head. They define the notion 'relativized head' as in (i).
(i) The headF (= head with respect to the feature F) of a word is the rightmost element of the word marked for the feature FThe difference between the notions 'head' and 'relativized head' is far from trivial. The notion 'head' is an absolute notion, in the sense that one constituent of a complex word is marked as the head, and features marked on this constituent undergo Feature Percolation. The notion 'relativized head' entails that a constituent can be the head with respect to one particular feature, but a non-head with respect to another. EXAMPLE: if the rightmost constituent has the feature [+F] and [uG] (where [uG] means 'not marked for feature G'), and its lefthand sister constituent has the feature [+G], the righthand constituent is the relativized head with respect to the feature [F], whereas the lefthand constituent is the relativized head with respect to the feature [G]. As a consequence the Feature Percolation Conventions percolate up the feature [+F] from the righthand constituent and [+G] from the lefthand one.
