Laurent Richard. Past Participles from Latin to Romance

University of California Press, 1999. — 602 p. — (University of California publications in linguistics 133).A detailed study of the history of past participle morphology in Romance. From the introduction of the book: "Since the time of the Technē Grammatikē ascribed to Dionysius Thrax (ca. 100 BCE), participles have been acknowledged in the West as a part of speech that shares features of verbs and nouns. It is astonishing how little the standard survey of Latin or Romance takes account of the morphology of past participles. It is clear, therefore, that the morphology of past participles in neo-Latin has not yet been investigated in historical depth, or with the comparative breadth across the Romance-speaking areas of Europe (ROMANIA) that the topic deserves. In the present work, I sketch the Latin system of p.p. formation and review how later speakers have kept or lost or transformed the inventory of past participles left to them by the legionaires."
