Quite often the interaction between groups is socially unequal, and this is reflected in the fact that in many cases borrowing of words or constructions goes mostly or entirely in one direction, from the more powerful or prestigious group to the less favored one. The languages of socially subordinated groups may from quite an early period of contact provide terminology for objects or practices with which speakers of the more powerful group were previously unfamiliar, but the effects of contact in that direction may not progress any further than this. In some cases, as with the Dharug language of Sydney, Australia, the source of some of the earliest loans from Indigenous Australian languages into English, the fate of the language system is extinction after the obliteration of many of its speakers. The remainder shifted to varieties of English, the language of the people who had suppressed them.
