In Cantonese phonology, a close relationship exists between the nasal codas (-m, -n, -ŋ) and the stop codas (-p, -t, -k). These two types of codas can also be classified into three homorganic pairs: the bilabial m/p, the dental n/t, and the velar ŋ/k. Their close association is best evidenced by the very fact that all stop sounds come from nasal sounds.^{[citation needed]}
