Nesting Partner
A partner with whom one shares a household — distinguished from non-cohabiting partners in polyamorous and ENM contexts. The term is preferred over "primary" by people who reject hierarchical labelling but want to acknowledge the practical realities of living together.
Wikipedia's polyamory terminology entry defines a nesting partner as a partner with whom one intends to live together long-term — "not necessarily in the same bed, but possibly where commitment is prioritized over passion." The label is descriptive rather than evaluative: it documents a logistical fact (shared address, shared bills, shared mortgage or lease) without ranking that partner above any others.
The term gained traction as a deliberate alternative to "primary" because primary implies a hierarchy that many practitioners — particularly those who identify as solo polyamorous or relationship anarchists — actively reject. Poly Dictionary notes that someone can have multiple nesting partners across multiple homes, and a nesting partner does not need to be a romantic or sexual partner at all; the load-bearing definition is shared domestic life. Satellite partners, by contrast, sit outside the nest.
In practice, naming a nesting partner clarifies expectations rather than assigning rank. Cohabitation creates real entanglements — finances, kids, pets, holiday schedules — that affect availability for other partners regardless of how flat the relationship hierarchy is on paper, and the term lets non-cohabiting partners understand that asymmetry without inferring that they are emotionally lesser.

- Primary Partner — In hierarchical polyamory and many open-relationship structures, the partner who has the most central, established, and prioritized relationship — typically a long-term spouse or live-in. Not all non-monogamous people use primary/secondary language; relationship-anarchy and egalitarian poly explicitly reject it.
- Polyamory — The practice of maintaining multiple simultaneous romantic relationships with the knowledge and consent of everyone involved. Distinct from swinging in that polyamory emphasizes emotional and romantic bonds, not just sexual ones.
- Relationship Anarchy — A philosophy that rejects rules-based hierarchies between relationships, treating each connection on its own terms rather than slotting it into a pre-defined category. Relationship anarchists typically refuse "primary/secondary" labels and emphasize personal autonomy over social scripts.
