Person restrictions in Basque intransitives

I discuss the extension of the Person Case Constraint analysis of 1/2 :nor-nori-nork gaps (*eraman naiozu) to 1/2 :nor-nori gaps (hurbiltzen/*gustatzen natzaio). According to it, all and only datives c-commanding a 1st/2nd person absolutive block its agreement. Three aspects of this hypothesis are examined : (i) differences with morphological gaps, found in western varieties for all 1/2 :nor-nori forms ; (ii) coverage across the diversity of nor-nori structures, notably complex ones and detransitivisations ; (iii) tension with the applicative agreement morphology of nonapplicative datives.
