A revival of interest in morphology has occurred during recent years. The Yearbook of Morphology, published since 1988, has proven to be an eminent support for this upswing of morphological research, since it contains articles on topics which are central in the current theoretical debates which are frequently referred to.In the Yearbook of Morphology 2004 a number of papers is devoted to the topic ‘morphology and linguistic typology’. These papers were presented at the Fourth Mediterranean Morphology Meeting in Catania, in September 2003. Within the context of this denominator, a number of issues are discussed wich bear upon universals and typology. These issues include: universals and diachrony, sign language, syncretism, periphrasis, etc.
