The volume deals with the emergence of verb morphology in children during their second and early third year of life from a cross-linguistic perspective. It covers 15 contributions - each analyzing one single language - based on parallel longitudinal investigations of children with parallel methodology and macrostructure in representation. The main question addressed is: How do children detect morphology and construct first subsystems of verbal inflection? The focus lies on the transition from a premorphological phase to a protomorphological phase. The main proposal consists in the concept of miniparadigms and of their relation to morpho-syntactic developments in early first language acquisition.
