Belonging is an ambiguous concept that has tended to escape the rigorous theorization of other key concepts in geography. Rather than viewing this as a weakness, I turn to weak theory to consider belonging in generative ways, to reflect on the texture of how it is felt, used and practised. I particularly consider its emotional aspects and the ways it is performed by myriad humans and more-than-humans. I conclude with an ontological consideration. Understanding belonging as emergent co-becoming may allow for hopeful and inclusive geographies that are diversely care-ing and careful.
