Canadian Shift
From Wikipedia, the free encyclopedia
The Canadian Shift is a linguistic chain shift, first identified in 1995, found among many anglophone Canadians.
This feature is not found in the Atlantic Provinces, east of Quebec; it is only found in Ontario and farther west. It is triggered by the cot-caught merger. As one vowel enroaches upon the space of another, the adjacent vowel in turn experiences a movement in order to maximize phonemic differentiation. The vowels in the words cot /kɒt/ and caught /kɔt/ merge to [kɔt].
- The /æ/ of bat is retracted to [a]
- The /ɛ/ of bet shifts to [æ]
- The /ɪ/ in bit then shifts to the [ɛ] (as in bet)
