This volume contains ten revised and expanded papers selected from the dozens presented at the last Michigan-Berkeley Germanic Linguistics Roundtable, five contributions each from syntax (by Werner Abraham, Sarah Fagan, Isabella Barbier, John te Velde, and Ruth Lanouette) and historical linguistics (by Garry Davis and Gregory Iverson, Mary Niepokuj, Neil Jacobs, Edgar Polome, and David Fertig). The authors start from current theoretical discussions in syntactic and diachronic research, using theory to address longstanding but still current problems in Germanic linguistics, from clitic placement and verb-second phenomena through the Verscharfung to the Twaddellian view of umlaut. Each contribution relies on careful sifting of data situated in the relevant comparative context, Germanic, Indo-European and cross-linguistic.
