Ngaphambi kokuqala, kunconywa ukuthambisa phansi, ngale ndlela sizovimbela imbewu ukuthi ingawi futhi ifinyelele ekujuleni lapho ukuhluma kwabo kungaba nzima noma kungenzeki nhlobo. Uma usebenzisa izimbiza ngazinye, okuhle ukubeka izimbewu ezimbili ngembiza ngayinye, uma zombili zihluma ungasusa ezibuthakathaka ugcine enye.
