Nangona ihlala ibizwa ngokuba linani, isenokuquka oonobumba, nangona igqibela ngamanani. Awona manani aluphawu ngokwenene kwimveliso eqhutywayo ngalawo angenakwandiswa lelinye inani, okanye ngomnye umahluko, ukusuka kwelinye inani ukuya kwelinye. Izinto eziphawulwayo ke zingaphawulwa ngeekhowudi zoonobumba manani, kodwa linye kuphela kweli eliyakuba linani lokuphawula; amanye amana ukubizwa ngokuba ngamanani anominal, kwaye ngawo anokubonisa amalungu ezinto, abonakalise ngokungqalileyo okufakelweyo, njalo njalo.
