Ukulwangisa ngendlela elula yikuguquka kwabongwaqa besiba ngolwangeni. Ukulwangisa kutshengisa ukuguquka kwabo ngwaqa besiba ngolwangeni. Inguquko le yenzeka kubondebembili loba onsinini babe ngolwangeni kanje: umthapho – umthatsho; incwadi –incwajana. Kulezi izibonelo kutshengisa ukuthi undebembili u/p/ lonsinini /d/ baphenduke baba ngolwangeni/tsho/lo/j/.
Lapho kwenzeka khona ukulwangisa: Uma kuncitshiswa amabizo – inkabi –inkatshana, isigujana. – isigujana. Ekwakhiweni kwezandiso zendawo – umlomo – emlonyeni, umthapho – emthatsheni. Uma kusakhiwa impamposi yokwenziwa – phupha –phutshwa, thapha – thatshwa.
Uma kusakhiwa amabizo zigaba ezithize – ubu – +(a)la – utshwala, ubu – + (a)ani – utshani.
Okwenzakalayo uma kulwangiswa: Nxa kulwangiswa kuqalwa ngokungwaqazisa kube kikukandelana kwabongwaqa kudingeke ukulwangisa.
