This volume deals with the reconstructed morphology of Proto-Romance. It is the third in a series by this author. The first volume (1974, Elsevier) deals with the external history of the Romance languages: the conditions under which they developed, were used, and (in some instances) went out of use. The second volume (1976, Elsevier) treats the phonology of their common source, Proto-Romance. Together these three volumes aim to cast light, not only on Popular Latin speech by means of its surviving elements in the Romance languages, but also on the extent to which the comparative method can be regarded as valid and useful in instances where no attestations are available for a language as closely related to the reconstructed proto-language as high Classical Latin was to Proto-Romance.
