In sociolinguistics, the apparent-time hypothesis states that age-stratified variation in a linguistic form is often indicative of a change in progress. That is, if in a survey of a population, patterned differences between the speech of individuals 75 years old, 50 years old, and 25 years old may indicate changes that have occurred over the past 50 years. The apparent-time hypothesis depends on several assumptions: first, that a significantly broad sample is taken to be representative of the population; second, that vernacular speech is relatively stable in a given individual once that individual is past adolescence.
