Open front unrounded vowel to Near-open front unrounded vowel

The shift from the open central/back vowel [a] to the near-open front vowel [æ] is a common historical process known as fronting or palatalization. It frequently occurs when influenced by surrounding palatal consonants or through broad systemic vowel shifts.
