“…The distribution of front umlaut in the vocabulary is quite different, not only when the North and West Germanic branches are compared but likewise between more closely related daughters that both descend from the same main branch (Kiparsky 2009:12-16, 45-48). Hence, insofar as the relative chronology is concerned, the majority view today is that this sound change must have progressed in parallel, after the Northwest Germanic protolanguage broke up (Kiparsky 2009, Dresher 2018: §3.5, note 23, Schalin 2018:54, 58 with references). Against this background, it continues to be justified to pursue reconstruction of the Nordic umlauts internally, as is done in this paper.…”
