It was about one and a half years ago that I finally I arrived where I had always wanted to be and do what I had always wanted-- teach students, support small language communities and conduct research on African languages on my doorstep. The University of Cape Town and my new colleagues welcomed my efforts to establish the Centre for African Language Diversity-- CALDi as well as The African Language Archive-- TALA and I was recently appointed the Mellon Research Chair: African Language Diversity this initiative. The main aim of CALDi is to train young African scholars in descriptive linguistics and open up space for research into African languages at UCT with the hopes of countering the dominance of African linguistics outside the continent. It has been a great challenge for which my whole career has been a form of preparation...Read more

Language Acquisition and the Functional Category System
Research on spontaneous language acquisition both in children learning their mother tongue and in adults learning a second language has shown that language development proceeds in a stagewise manner. Learner utterances are accounted for in terms of so-called 'learner languages'. Learner languages of both children and adults are language systems that are initially rather simple. The present monograph shows how these learner languages develop both in child L1 and in adult L2 Dutch. At the initial stage of both L1 and L2 Dutch, learner systems are lexical systems. This means that utterance structure is determined by the lexical projection of a predicate-argument structure, while the functional properties of the target language are absent. At some point in acquisition, this lexical-semantic system develops into a target-like system. With this target-like system, learners have reached a stage at which their language system has the morpho-syntactic features to express the functional properties of finiteness and topicality. Evidence of this is word order variation and the use of linguistic elements such as auxiliaries, tense, and agreement markers and determiners.
Looking at this process of language acquisition from a functional point of view, the author focuses on questions such as the following. What is the driving force behind the process that causes learners to give up a simple lexical-semantic system in favour of a functional-pragmatic one? What is the added value of linguistic features such as the morpho-syntactic properties of inflection, word order variation, and definiteness?
