What is nominal concord?
This process goes by at least two names: nominal concord (my preferred term) and adnominal agreement (due to, at least, Ranko Matasović).
If you're unfamiliar with this process, a prepublication draft of my survey article is here: Description and analyses of nominal concord (Parts I-II).
