Dan Flickinger: Transparent Heads

Head-complement structures in HPSG identify most properties of the phrase with those of the head daughter, except for that valence property (e.g. SUBCAT or COMPS) whose constraints are met by the non-head daughter(s) in the phrase. In this paper I present several phenomena in English syntax where idiosyncratic properties of a non-head daughter in a phrase must remain visible on the phrasal node, in order to preserve the strong version of the principle of locality in subcategorization. I propose a general formal mechanism to effect this occasional transparency of heads with respect to certain properties of their complements.
