From a sociological point of view it could mean the assimilation of ethno cultural minorities in Sri Lanka such as the Sri Lankan Tamils, Colombo Chetties and indigenous Veddas into the majority Sinhalese identity. It is specially noted with respect to Sinhalese speaking Catholics of the coastal areas of the island nation. Many noted elite families were supposedly Sinhalised during the pre colonial period from foreign origins.
