The social context was that of a few Austronesian men who settled on the outskirts of an East Trans-Fly group, intermarried, and whose children were either bilingual, or speakers of their mothers' language, with some knowledge of their fathers' language. The local people did not need to speak the traders' language, who in turn had to speak the local language. The children in turn would then speak the local language, with varying ability in the fathers' language, particularly in areas that were culturally important for the fathers.
