 However, in the instances Trudgill was able to document (e.g., first generation speakers of Tyssedal and Odda dialects of Norwegian), the speech of this generation still reflected considerable variability in use of marked forms, both between speakers and in the repertoire of individual speakers.It is the third generation that focuses the variations and stabilizes the dialect.Trudgill admits that there are cases where the focusing can take place in the first generation of native-born speakers and also instances where it might be in the fourth or even later generations.
