Morphomic patterns, suppletion, and the Romance morphological landscape
This chapter uses especially cases of suppletion in the history of Romance languages to illustrate the role of morphomic patterns in diachrony. It also places Romance verb morphology in the wider context of Romance inflexional morphology, including those of the noun and of the adjective. It observes that suppletion practically never assumes anything but a morphomic distribution and is practically limited to the verb. Comparison is made with some Italo-Romance and Daco-Romance varieties where suppletion is indeed (occasionally) found in the noun and adjective (and is usually not morphomic). The evidence suggests that speakers, faced with different ways of expressing identical lexical meaning, exploit whatever patterns of root allomorphy happen to be already available in the language. In the Romance verb these are only morphomic; in the noun and adjective such patterns are scarcely found at all, but where they are they tend to be aligned with number.
