Crosslinguistics and Linguistic Crossings in Northeast Asia includes articles which are arranged thematically into three sections. The papers in the first section deal with diachronic and areal aspects of the languages of the target region, with topics ranging from genetic taxonomy and reconstruction to areal similarities and contrasts. The papers in the second section deal more with synchronic typology and grammatical analysis, with a particular focus on nominalization, but on features such as incorporation and modality. Finally, the papers in the third section address the ethnopolitical and sociolinguistic situation of the endangered speech communities, with a focus on the phenomenon of language shift, but also on ethnic and linguistic identity issues.
