While identity research has given sustained attention to marginality, intersectionality, and the effects of power on identity, the formal interactional dynamics through which identities are constituted remain limited. I present identity entanglement as a useful framework for better understanding and articulating the relational complexities of identity. Using social pattern analysis, I examine intersectional, liminal, and antithetical identities through prior research, the media, and historical accounts, and model these marginal identities through the entanglement modes that characterize their interactions. In doing so, I develop a typology that provides new analytic tools for understanding the formal and nuanced dynamics of identity and marginality.
