Compare
Side-by-side comparisons.
The differences between adjacent ENM configurations matter, and the casual conflation of them produces a lot of confusion. 19 careful comparisons, each ending with a clear bottom-line.
Open relationshipvsPolyamory
Both are ethical non-monogamy. The clearest dividing line: whether 'partner' as a role is reserved for the central pair (open) or available across multiple connections (poly).
PolyamoryvsRelationship anarchy
Polyamory is a relationship configuration that allows multiple loving partnerships. Relationship anarchy is a broader philosophical position that rejects ranked hierarchies and inherited relationship scripts.
Solo polyamoryvsRelationship anarchy
Solo poly is a specific life-design (autonomy as centre, no nesting partner); RA is a broader philosophy. The two overlap significantly but are not the same thing.
Kitchen-table polyamoryvsParallel polyamory
Kitchen-table polyamory integrates the polycule socially; parallel polyamory keeps the relationships on separate tracks. Most polycules sit somewhere between, often at garden-party in the middle.
Hierarchical polyamoryvsNon-hierarchical polyamory
Hierarchical polyamory uses ranked tiers (primary/secondary) explicitly; non-hierarchical refuses them and uses descriptive language (nesting partner, anchor partner) for entwinement instead.
MonogamishvsOpen relationship
Monogamish treats outside connections as occasional named exceptions to a monogamous baseline; open relationships treat them as part of an ongoing structure.
PolyamoryvsPolygamy
Polyamory is a consent-based relationship orientation involving multiple loving partnerships. Polygamy is a legal-marriage configuration in which one person is married to multiple spouses, typically tied to religious or cultural traditions.
PolyfidelityvsPolyamory
Polyfidelity is a closed polycule — three or more committed partners with no openness to additional partners outside the group. It is a specific configuration within the broader polyamory umbrella.
LifeStylevsPolyamory
Polyamory centres multiple loving romantic relationships. The LifeStyle — also called swinging — centres recreational and social sexual connection within a community, while the primary romantic-partnership identity stays intact.
SwingingvsOpen relationship
Both keep a central couple while allowing outside sex. The difference is community and shape: swinging is an organised couples' social-and-sexual scene; an open relationship is a private arrangement between two people.
PolyamoryvsMonogamy
Monogamy commits to one romantic-sexual partner at a time; polyamory allows multiple loving partnerships at once with everyone's knowledge and consent. The dividing line is plurality of partners, not honesty or commitment — both require those.
Ethical non-monogamyvsCheating
The entire difference is consent. Ethical non-monogamy means everyone knows and agrees; cheating means breaking your relationship's agreements behind a partner's back. ENM relationships can still be cheated on — by breaking the agreements they set.
Solo polyamoryvsPolyamory
Solo polyamory is a form of polyamory that deliberately keeps autonomy at the centre — no nesting, no merging into a couple-unit — while polyamory broadly includes everything from couple-centred to fully entangled networks.
Relationship anarchyvsHierarchical polyamory
They sit at opposite ends of the ranking question. Hierarchical polyamory formally ranks relationships (primary, secondary); relationship anarchy refuses to rank them at all, including the romantic-over-platonic ranking most people take for granted.
MonogamishvsPolyamory
Monogamish is mostly-monogamous with rare, limited exceptions; polyamory is genuinely plural. One keeps a single central relationship with occasional outside sex; the other builds multiple loving partnerships.
Open relationshipvsRelationship anarchy
An open relationship keeps a central couple and opens it to outside sex; relationship anarchy rejects the idea of a central couple — and of ranking relationships — altogether.
AmbiamoryvsPolyamory
Polyamorous people want multiple loving partners; ambiamorous people are genuinely happy either monogamous or polyamorous, and can settle into whichever fits a given relationship.
Kitchen-table polyamoryvsGarden-party polyamory
Both describe how connected a polycule's members are, on a spectrum. Kitchen-table means everyone's comfortable hanging out like family; garden-party means everyone's friendly at occasions without sharing daily life.
Hierarchical polyamoryvsSolo polyamory
Hierarchical polyamory centres a ranked primary relationship; solo polyamory centres the individual and refuses to rank or merge. One organises around a couple, the other around personal autonomy.
