Resumen de The Romance plural isogloss and linguistic change: a comparative study of Romance nouns
Romance nouns show a well-known morphological isogloss. There are two groups of languages: those pluralizing by suffixing -s (such as Spanish), and those pluralizing by changing the quality of the final vowel (such as Italian). In this paper, I propose an explanation of this isogloss. More precisely, I argue that the cross-linguistic diversity within Romance depends on morpho-phonological parameters on the structure of the noun. These parameters consist of language-particular restrictions on the form of the (nominal) roots and the exponents of gender and number.
