The investigation of Old English phonology has been incessant over the decades and carried out from the vantage point of many different theoretical perspectives, but it remains a remarkable fact of our neogrammarian legacy that fundamental aspects of their Old English analyses have weathered the changing theoretical winds particularly well. This high degree of consensus allows us to present a very broad, relatively uncontroversial overview of many fundamental aspects of OE phonology. At the same time, of course, problematic areas remain, and some controversies of perennial interest are indicated. Grammatik ('Old English Grammar') in 1882, and other grammars and classic works strongly influenced by the neogrammarian perspective followed, such as Sweet (1888), Bü lbring (1902), Wright and Wright (1925), Campbell (1959), and Brunner (1965 -the last revision of Sievers's grammar).

Although there were many areas of disagreement, for the main part our classic grammars and handbooks reflect a kind of rough neogrammarian consensus Alex Bergs and Laurel Brinton 2012, Historical Linguistics of English (HSK 34.1), de Gruyter, 255-272
