Dabei sind Forschungen zu Bantu- sprachen vergleichsweise gering in Anbetracht der Große¨ der Sprachfamilie (circa 300 Sprachen). Die vorliegende Dissertation untersucht daher den grammatischen Ausdruck der informationsstrukturellen Kategorie Fokus im Nord-Sotho, einer Bantusprache der Republik Sudafrika.¨ Sie bietet eine systematische Untersuchung zur Verankerung von in- formationsstrukturellen Kategorien in der Grammatik dieser Sprache und verwendet dafur¨ eine etablierte Methodologie. Dadurch soll einerseits das Verstandnis¨ erweitert werden, wie und ob die Kategorie Fokus in den Sprachen der Welt markiert ist, und zum anderen sollen die gewonnenen Daten einen sprachubergreifenden¨ Vergleich erlauben. Die Hauptthese dieser Dissertation ist, dass Nord-Sotho keinen obligatorischen Ge- brauch von grammatischen Mitteln zur Markierung von Fokus macht, weder in der Syn- tax noch in der Prosodie oder Morphologie. Trotzdem strukturiert diese Sprache eine Außerung¨.
