Polyamory Glossary: 60+ Essential Terms Every ENM Person Should Know

Why ENM Has Its Own Language

Ethical non-monogamy has developed a specialized vocabulary because the mainstream cultural vocabulary doesn't have words for the experiences ENM practitioners have. Terms like "metamour," "compersion," and "anchor partner" name real things that needed naming. This glossary defines 60+ of the most important terms in ENM culture.

A

Anchor Partner — A partner who provides stability and grounding, characterized by deep trust and consistency, without necessarily implying cohabitation or hierarchical "primary" status.

Attachment Style — The characteristic pattern of relating to intimate partners, rooted in early childhood bonding experiences. Primary styles: secure, anxious, avoidant, and disorganized.

B

Boundary — A limit that applies to yourself and your own behavior. Distinct from a rule (which governs another person's behavior).

Branching — A network growth pattern in which one person's new connection brings new people into the broader polycule network.

C

Closed Relationship / Closed Polycule — An ENM arrangement in which members have agreed not to add new partners outside the current group. Also called polyfidelity.

CNM (Consensual Non-Monogamy) — The umbrella term for any relationship structure in which all people involved knowingly consent to non-exclusive connections.

Comet — A partner who appears periodically but with genuine depth — someone you may not see often but who is meaningfully present when you do connect.

Compersion — The feeling of joy experienced when a partner experiences joy with another person. Often described as the opposite of jealousy.

Couple Privilege — The advantages that long-established couples have over additional partners in hierarchical polyamory structures — including power over rules, veto authority, and relationship priority.

D

DADT (Don't Ask, Don't Tell) — An ENM arrangement in which partners agree not to share or ask for details about outside relationships.

Dyad — A two-person relationship.

E

ENM (Ethical Non-Monogamy) — Any consensual relationship structure involving emotional or romantic connections with more than one person.

Escalator (Relationship Escalator) — The conventional, socially expected progression of romantic relationships: dating, exclusivity, cohabitation, marriage, children. ENM communities often "step off the escalator."

F

Fluid Bonding — The practice of engaging in sexual activity without barrier protection with a specific partner, within an explicitly agreed STI testing and disclosure framework.

Freestanding Relationship — A relationship that exists independently, without being defined primarily in relation to another relationship.

G

Garden Party Polyamory — A variation of kitchen table polyamory where all metamours are cordial and respectful but don't necessarily develop close friendships.

Galaxy Brain — The tendency in polyamory to reason oneself into situations that seem logically justified but are actually harmful or unethical.

H

Hinge — The person in a V-shaped relationship who is the shared connection between partners who may not have a direct relationship with each other.

Hierarchical Polyamory — A polyamory structure in which relationships are explicitly ranked by priority, typically using "primary," "secondary," and sometimes "tertiary" designations.

I

Informed Consent — Consent given with full knowledge of what one is agreeing to. A significant ethical standard in ENM.

J

Jealousy — The emotional response to perceived threat to a valued relationship. In ENM, generally understood as information about an underlying need or fear.

K

Kitchen Table Polyamory (KTP) — A network structure in which all members of a polycule are friendly enough to comfortably share a meal together. Emphasizes community and integration.

L

Limerence — An intense, often involuntary state of romantic attraction and longing. Related to NRE but with a more obsessive quality.

M

Metamour — Your partner's other partner. A person you are connected to through a shared partner, but with whom you may or may not have your own independent relationship.

Mono/Poly — A relationship structure in which one partner is monogamous and the other is polyamorous.

N

Nesting Partner — A partner with whom you share a home. Separates cohabitation from hierarchical implications.

Non-Hierarchical Polyamory — A polyamory approach that rejects the explicit ranking of relationships by priority or status.

NRE (New Relationship Energy) — The heightened excitement and emotional intensity characteristic of early-stage romantic connections. Can temporarily distort judgment if not managed consciously.

O

Open Relationship — A broad term for a relationship in which partners may have sexual and/or romantic connections outside the primary partnership.

P

Parallel Polyamory — A network structure in which individual relationships exist separately, with limited integration between metamours or across the broader network.

Polycule — The full network of people connected through polyamorous relationships — partners, metamours, and their connections.

Polyfidelity — A closed polyamorous arrangement in which a defined group of people are committed to each other exclusively.

Polysaturation — The state of having reached the limit of one's emotional and practical bandwidth for new relationships.

Primary Partner — In hierarchical polyamory, the partner with the highest structural priority. Not all polyamorous people use primary designations.

Q

Quad — A relationship network of four people, typically two couples whose members are also romantically connected with each other.

R

Relationship Anarchy (RA) — A philosophy that rejects relationship hierarchies, labels, and social scripts. Each relationship is defined on its own terms.

S

Secondary Partner — In hierarchical polyamory, a partner with lower structural priority than a primary partner.

Solo Polyamory — A polyamory practice in which a person maintains multiple relationships while prioritizing personal independence.

T

Triad — A relationship network of three people who are all romantically connected to each other.

V

V (Vee) — A relationship structure in which one person (the "hinge") is romantically connected to two partners who are not romantically connected to each other.

Veto Power — An agreement in which one partner can demand the ending of another partner's relationship. Widely considered unethical in ENM communities.

W

Wibble — A mild, uncomfortable feeling when a partner's other connection is mentioned — not quite jealousy, but a small emotional bump. Naming it makes it easier to address.
