Koineization
It is the third generation that focuses the variations and stabilizes the dialect. Trudgill admits cases in which the focusing takes place in the first generation of native-born speakers and also instances that might be only in the fourth or even later generations. The dialect in its emerging state, a state marked by the heterogeneity of forms, is called by Trudgill an interdialect and is often called an interlanguage in other dialect studies.
