5. 4 Components of a sequence of linguistic changes 1.Triggering events: the first in the chain of causally connected events 2.Governing principles: constraints that determine the unidirectional character of changes 3.Forks in the road: alternate pathways of change that differentiate sister dialects 4.Driving forces: factors that lead to the continued incrementation of the changes 5.Re-analysis: the process that leads to the uniform distribution of the changes across the speech community.

6. 5 Two ways of looking at the problems of language change 1.The actuation problem 2.Constraints problem 3.The transition problem 4.The embedding problem 5.The evaluation problem Triggering events Governing principles Forks in the road Driving forces Re-analysis Weinreich, Labov & Herzog 1968 Accounting for changes This presentation Accounting for sequences of changes

24. 23 In chain shifts, I. Long vowels rise. II. Short nuclei fall. II. Back nuclei shift to the front. --Labov, Yaeger & Steiner 1972 General principles of chain shifting
