Age differences in sociolinguistic

Hello everyone.

I'm going to write notes about age differences in sociolinguistic. 

I read many information we can summarize them in points.

1- Age-variation: is a stable variation which varies within a population based on age. That is, speakers of a particular age will use a specific linguistic form in successive generations. 

2- Recent longitudinal studies in sociolinguistics have confirmed that some adults change their speech as they age, and that changes can occur at many levels of the grammar. 

3- We find that children have linguistics mistakes because they imitate adults speech. When they grow up their speech becomes closely as adults' speech. 

4- Soci- olinguists have attempted to classify the scenarios in which individual linguistic change is possible.

5- The term ‘age grading’ has been most frequently applied to a subset of cases in which the individual responds to the pressures of the standard language market by mark- ing the transition to middle adulthood with more conservative speech patterns than they had previously employed as adolescents and young adults.
