Abstract
David Rycroft observed in his studies of Swati tonal structure that it is unique amongst the Nguni languages in having lexically conditioned cases of tonal depression following non-depressor consonants such as /f s sh c t/. Production and perception data suggest that such tones are not the same as rising high tones following depressor consonants but are sui generis. Swati therefore remains unique, but the tonal facts need re-analysis in the light of the present findings.
David Rycroft se studies oor die toonstruktuur van Swati het getoon dat hierdie taal uniek is onder die Ngu-ni-tale omdat daar voorbeelde van woord-bepaalde toondaling né nie-dalende konsonante soos /f s sh c t/ voorkom. Deur middel van produksieen persepsiedata word bewys dat sulke voorbeelde nie dieselfde is as stygende hoë tone né dalende konsonante nie, maar wel sui generis is. Swati bly dus uniek, maar die herontleding van toonaard word bevestig deur huidige bevindings.
