The volume under review brings together nine scholars from diverse subfields of historical linguistics. As the title and subtitle suggest, the area covered by the contributions is varied in terms of topic, language, and era, and while the papers offer valuable contributions to the respective fields, the thematic incoherence is notable and the preface does not offer much in the way of a unifying framework to make the various contributions reflect on each other.
As the editors state, the volume is not a typical conference proceedings, and the pronounced differences in topic and scope result from the selection of abstracts accepted for the eponymous conference which was prevented from happening by the COVID 19 pandemics.
