The evolution of the genitive noun phrase in early Middle English
… genitive system. It is through these individual "micro-systems" that we can see the details of the development of the genitive noun phrase, details which show that the genitive noun phrase did not develop uniformly throughout the country, but that speakers had several options for re-interpreting …
