Relational means indicating relation(s) or relationship; concerning the way in which two or more people or things are connected. It would follow, therefore, that relationality means ‘being related to’; ‘in a relationship’; ‘connectedness’; but try Yeung (2005) TIBG 30, 1, who describes relationality as an ‘essential quality embedded in an iterative process of drawing interconnections between two or more discrete categories and phenomena that may not necessarily be binaries’.

Smith et al. (Open University) shed some light: ‘one of the ways that geographers explore relationality is not simply by making assertions or pronouncements, but by actually tracking the practices through which geographically extensive linkages are established and sustained. Following flows through specific networks and nodes, researchers “flesh out” the causal chains that implicate distant lives.’ Hopkins and Pain (2007) Area 39, 3 also help: ‘relationality does not just pose interesting questions about age, but marks a fundamental change in the way we approach and think about it, focusing more widely on families, generations and interactions’; and Sparke (2008) PHG 32, 3 writes that local regions and places should be studied ‘with attention to the ways in which they are interarticulated with global space-spanning ties and traces’.
