In this volume, Marcin Krygier seeks to chronicle the loss of morphological alternations resulting from Old English i-umlaut in the inflectional systems of the various dialects of Middle English. The author argues that while the extent of i-umlaut in Old English is well researched, no detailed analysis of the subsequent process of leveling of i-umlaut alternations in Middle English has been produced. To address this lack of analysis of the Middle English i-umlaut alternations, the author organizes the volume into three main parts.
