Intergenerational communication and aging is a thriving interdisciplinary, methodologically diverse field having significant implications for understanding the aging process. This opening article to the special issue provides a brief overview of this research domain, with particular attention to theoretical practices within it. Communication accommodation theory (CAT) is introduced given it has provided a foundation for other well-cited models of communication and aging. In so doing, a couple of the CAT principles are elaborated, based on recent work on age meta-stereotyping and intergroup felt understanding. CAT is also a component of the influential “communication ecology model of successful aging” and, after exploring some of its tenets, its visually schematic representation is elaborated as well as connections speculated regarding its relationship with the communicative lives of SuperAgers. Thereafter, highlights emerging from the articles in this special issue that follow are drawn out.
