A series of historical sound changes. Two kinds of chain shift have been hypothesised:<\/p>\n

  1. Drag-chain: a change in quality over time leaves a phonetic gap into which another unit moves, which in turn leaves a phonetic gap and so on. For example, the English Great Vowel Shift<\/a> could be explained by positing the first event in time to be the diphthongisation of the high<\/a> vowels. This left a gap in the vowel system into which the high-mid<\/a> vowels moved and so on.<\/li>\n
  2. Push-chain: a change in quality over time means that one phonological unit becomes too close to another. The second unit begins to move until it too becomes too close to a third and so on. Under this hypothesis, the English Great Vowel Shift began with a raising of the low vowels, which exerted pressure on the mid-vowels and so on. Finally, the high vowels became diphthongs<\/a>.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
