Ngokungafani nezidlulisi zeleveli yoketshezi engaphansi kwamanzi evamile, isebenzisa inzwa engaxhumani ngokuqondile nendawo elinganisiwe. Esikhundleni salokho, idlulisela izinguquko zengcindezi ngezinga lomoya. Ukufakwa kweshubhu lomhlahlandlela wokucindezela kuvimbela ukuvaleka kwenzwa nokugqwala, kunwebe ubude bempilo yenzwa. Lo mklamo uwenza afaneleke ikakhulukazi ukulinganisa amazinga okushisa aphezulu kanye nezicelo zokukhuculula indle.
