This volume brings together insights from leading scholars in the field of grammatical aspect to examine the multifaceted nature of this pivotal linguistic resource used to express temporal meaning. The contributors explore the many ways in which linguistic research can move beyond canonical semantic analyses of aspect, which still focus to a great extent on objective temporal features of what can be called 'situation models', i.e. integrated cognitive representations of designated states of affairs. The chapters in this volume widen this outlook by concentrating on less typical contexts in which aspectual constructions are used, e.g. for affective purposes, to mark the epistemic status of situations, or to shape narrative structures. This focus on non-prototypicality is also reflected in the languages investigated, many of which are understudied with respect to their aspectual constructions, including several African languages and the sign language Kata Kolok. The volume adopts a multidisciplinary methodological approach, and introduces possible directions for future research based on experimental studies, fieldwork research, and translation mining.
