Open-mid front unrounded vowel to Near-open front unrounded vowel

The shift from the open-mid front vowel [ɛ] (the DRESS vowel) to the near-open front vowel [æ] (the TRAP vowel) is a hallmark of vowel lowering in several modern English chain shifts. As the historical [æ] vowel moves back or down, it creates a 'pull chain' that draws the [ɛ] vowel down into its vacated space.
