The Use of Definite Articles in Romance Languages: Diffusion or Independent Development

Over the centuries, definite articles in Romance languages have expanded their use to include generic, collective, and abstract nouns, essentially becoming noun markers. This usage is not confined to just a few languages, either, but is found in most, if not all, Romance languages, major and minor. This thesis examines the question of how this came to be, whether through diffusion from one language to all others, or through independent parallel development.
