Ngamanye amazwi, isimo esinezici eziningi yileso esihilela ukusebenzisana kwezinto ezihlukahlukene noma izakhi, futhi umphumela uwumphumela wemiphumela ehlangene yalezi zici. Leli gama livame ukusetshenziswa emikhakheni efana nesayensi, imithi, ingqondo, nesayensi yezenhlalakahle, lapho izinhlelo eziyinkimbinkimbi noma izinkinga zihlaziywa futhi zifundwe.
