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

Blocking and Complementarity in Phonological Theory
Disjunctive application is a type of interaction between phonological mappings that has received special attention since the inception of generative phonology (Chomsky & Halle 1968) and has significantly impacted research in other subfields in linguistics. The principle commonly held to be responsible for disjunctive application, the Elsewhere Condition (Kiparsky 1973), is argued in this book to be little more than a collection of necessary stipulations within Chomsky & Halle's original SPE framework. By contrast, disjunctive application is shown to follow automatically from the most basic assumptions of Optimality Theory (Prince & Smolensky 1993), with no added stipulations necessary.
The stage for these demonstrations is set with in-depth discussion of the history and analysis of blocking interactions, of which disjunctive application is a special case. The distinguishing feature of disjunctive application is shown to be complementarity. The analyses of two types of complementarity (allophonic or ‘unbounded’ complementary distribution as opposed to ‘bounded’ complementary distribution) in both SPE and Optimality Theory are discussed in detail, and it is shown that both have been analyzed very differently in SPE but very similarly in Optimality Theory.
The various stipulated components of the Elsewhere Condition are then discussed and contrasted with the lack of any such stipulation in Optimality Theory. This is followed by a proof of two theorems within Optimality Theory that solidify the result that two mappings in a particular formal relation to each other are bound to apply in complementary fashion.
