A well-known example is the Great Vowel Shift, which was a multiple shift that affected all of the long vowels in Middle English. The alter to the front vowels may be summarized as follows:

A drag chain or pull chain is a chain shift in which the phoneme at the "leading" edge of the chain make different first. In the example above, the chain shift would be a pull chain if /i:/ changed to /aɪ/ first, opening up a space at the position of [i], which /e:/ then moved to fill. A push chain is a chain shift in which the phoneme at the "end" of the chain moves first: in this example, if /a/ moved toward [e], a "crowding" issue would be created in addition to /e:/ would thus continue toward [i], as well as so forth. it is for not known which phonemes changed first during the Great Vowel Shift; numerous scholars believe the high vowels such(a) as /i:/ started the shift, but somethat the low vowels, such(a) as /a/, may earn shifted first.

Examples

During the Great Vowel Shift in the 15th and 16th centuries, any of the long vowels of Middle English, which correspond to tense vowels in innovative English, shifted pronunciation. The changes can be summarized as follows:
