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.

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

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

24

In chain shifts,

I. Tense nuclei rise along a peripheral track

II. Lax nuclei fall along a non-peripheral track

General principles of chain shifting

25

Phonemes co-existing in a language tend naturally to optimize

the possibilities that are available from the speech organs; they

tend to be as distant from their neighbors as possible while

remaining easy to articulate and easy to perceive. . .
