Gradualness of Grammaticalization and Abrupt Change Reconciled: Evidence from Microvariation in Romance

Grammaticalization has long been understood as a process that takes place gradually, but within it, discrete and abrupt changes take place. This tension has been reconciled by claiming that the semblance of a gradual process is given by different parts of a construction undergoing changes at different points in time. Focusing on synchronic microvariation as gradience, this article discusses cases of clitic loss in four Romance varieties (Brazilian Portuguese, Raeto-Romance, some northeastern Italo-Romance varieties, and French), and identifies common patterns in the cells of the paradigms that are most vulnerable to the process of loss. Relating the grammatical and semantic properties of these cells to established typological hierarchies, the paper explores how general cognitive principles can account for the key properties of gradualness and gradience and, ultimately, language change.
