This book explores how studies of language and aging can be applied to build an aging-friendly society, drawing on the socio-pragmatic turn in language and aging to examine the perspectives of older adults experiencing aging through a linguistic lens. Research on the phenomenon and mechanisms of language in aging can provide older adults with language training, increase their active aging, and offer improved information communication channels for an aging society, which will bring a series of clinical and social benefits to handle problems in aging and language across the world. This book will be of interest to researchers in linguistics, sociology, gerontology and related fields.
