This is the first book on the acquisition of the German case system by foreign language learners. It explores how learners in their interlanguage progress from the total absence to the presence of a case system. This development is characterized by an evolvement from marking the argument’s position to marking the argument’s actual function. Theoretically couched within Processability Theory, the book deals with the feature unification and the mapping processes involved in case marking, and critically examines previous findings on German case acquisition. Empirically, the book consists of longitudinal data of 11 foreign language learners of German, which was collected over a period of 2 years. This book will be useful to anyone interested in the acquisition of German and in the acquisition of case systems in general.

The Acquisition of German: Introducing Organic Grammar brings together work on the acquisition of German from over four decades of child L1 and immigrant L2 learner studies. The book’s major feature is new longitudinal data from three secondary school students who began an exchange year in Germany with no German knowledge and attained fluency. Their naturalistic acquisition process — with a succession of stages described for the first time in L2 acquisition — is highly similar to that of younger learners. This has important implications for German teaching and for the theory of Universal Grammar and acquisition. Organic Grammar, a variant of generative syntax, is offered as a practical alternative to Chomsky’s Minimalism. The analysis focuses on extensive monthly samples of the three students’ German development in an input-rich environment. Similar to previous studies, the teenagers build syntactic structure from the bottom up. Two acquired correct word order by the end of the year, the third, who had greater conscious awareness of German grammar, had a divergent route of development, suggesting that language awareness can alter a natural developmental path. The results are addressed in light of recent debates in child-adult differences.

This study deals with variation in grammar both from a theoretical and an empirical point of view. In Part I (Chaps. 1-4), an attempt is made to char acterize this phenomenon within the broader context of what might be called the "fluctuating character of natu'ral language", and to develop suitable and precise descriptive techniques that account for it. The method which is pro posed here is called "variety grammar" - roughly speaking, this is a formal grammar with probabilistic weighting for an ordered set of varieties, such as dialects, sociolects, registers, or developmental stages. In Part II (Chaps. 5-8), this technique is applied to an important area of grammatical variation - to the process of second language acquisition in social context, based on a large investigation of the language behavior of foreign migrant workers acquiring German through everyday contacts. We have tried to characterize their "developing grammars" and to relate this complex developmental process to social and individual factors that determine it.

This study of gender was conceived when I first took up the position of lecturer in linguistics at the University of Tiibingen in 1975. My particular in terest in gender arose out of the work with German children and adults con ducted in the context of preparing my doctoral dissertation for the University of York; my position at the University of Tiibingen has given me the opportunity to carry out the necessary research in both Germany and Britain. The empirical investigations reported in this study were begun in my first year in Tiibingen and continued over a period of 7 years. In this connection, I would like to express my thanks to the staff and pupils of all the schools who participated in the testing: Kindergarten Waldhauser-Ost, Kindergarten Winkelwiese, Grundschule Wanne, Grundschule Waldhauser-Ost, and Albert Schweitzer Schule (Tiibingen); Somerford Junior and Infants School and Twynham Junior and Infants School (Christchurch, GB); Burdyke Infants, Badger Hill Junior and Infants School and Joseph Rowntree Junior School (York, GB). Thanks must also go to the families of Georg, Hanna and Gisela and of course to the children themselves, who allowed the intrusion of recording equipment so regularly into their homes. I am also grateful to the staff and students of the Universities of Tfibingen, York and Manchester who cooperated in several of the investigations.
