This book analyses three phenomena of Romance Morphology. The first is event nominalization in modern European Spanish and Portuguese and the role of blocking concerning the suffix rivalry of {-miento/-mento} and {-cion/-cao}. The second are Romance conjugation classes in modern European Portuguese in comparison to Classical Latin and other Romance Languages such as Asturian, Galician, Standard Italian, Sicilian and modern European Spanish. The third phenomena are syncretisms in Italo- and Gallo-Romance, their treatment in morphological models and their relation to syntax. The analyses are made on the basis of detailed corpus studies and evaluated against the background of current morphological models."
