Relativized head
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 F
The 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.
