Morphological autonomy and the long-term vitality of morphomes: stem-final consonant loss in Romance verbs and paradigmatic analogy

Abstract

AbstractMorphologists of different backgrounds disagree with respect to the degree of autonomy of the morphological component of language from syntax and semantics. A precise and objective quantification of the diachronic productivity of Romance morphomes is the piece of evidence most crucially missing from this debate. On the basis of 502 morphophonological innovations associated with the loss of stem-final consonants across 63 Romance varieties, this paper quantifies the degree of productivity of different morphomes (the N pattern is found to be the most productive one) and of morphomic templates generally (15% of novel stem alternations are found to abide by them). Although a strong attraction effect is detectable for morphomes, the numbers suggest that the morphological autonomy and longevity of stem alternations in the family might have been somewhat overstated. For an optimal account of the morphological innovations observed, reference to inherited morphomic structure, semantic structure, and to frequency of use are needed in similar proportions.
