What Is a Metamour? Meaning, Examples & Relationship Tips
A metamour is your partner's other partner: someone your partner is dating, but you are not dating yourself. The term is most often used in polyamory and other consensually non-monogamous relationships. For example, if Alice dates Bob and Charlie, while Bob and Charlie do not date each other, Bob and Charlie are metamours.
Metamour is pronounced roughly MET-uh-mor (UK /ˈmet.ə.mɔːr/, US /ˈmet̬.ə.mɔːr/). The plural is metamours, and people often shorten the word to meta or metas. You can hear both pronunciations in the Cambridge Dictionary entry for metamour.
A Simple Metamour Example
Here is the relationship structure at a glance:
| Person | Direct relationship | Role in this example |
|---|---|---|
| Alice | Dates Bob and Charlie | The hinge, because she connects two relationships |
| Bob | Dates Alice, not Charlie | Charlie's metamour |
| Charlie | Dates Alice, not Bob | Bob's metamour |
Together, Alice, Bob, and Charlie form a V-shaped polycule. Bob and Charlie can be friends, acquaintances, or complete strangers and still be metamours; the word describes their indirect connection, not how close they are.
If Bob and Charlie also began dating each other, they would become direct partners. People may still acknowledge that they first met as metamours, but “partner” would now describe their relationship more clearly.

Where Does the Word Metamour Come From?
Metamour is a modern English coinage built from meta- and (par)amour. Dictionary.com records it from 1995 to 2000 and analyzes it as “meta- + (par)amour”. The word's construction suggests a lover connected through another love, although that is an explanation of its parts rather than proof of one exact coiner or moment of invention.
That modern history matters because confident stories about who invented “metamour” are difficult to substantiate. It is safer to say the term emerged in polyamorous communities in the late 1990s and became a convenient way to name a relationship that ordinary English otherwise describes with a clumsy phrase: “my partner's partner.”
The standard spelling is metamour. You may occasionally see metamor or metamore, but major English-language references use metamour.
Metamour vs Hinge, Paramour, Polycule, and Telemour
These terms describe different people or levels of a relationship network:
| Term | What it means | In the Alice, Bob, and Charlie example |
|---|---|---|
| Metamour | Your partner's partner, whom you are not dating | Bob and Charlie are metamours |
| Hinge | The person connecting two partners in a V | Alice is the hinge |
| Paramour | A person you are directly romantically or sexually involved with; the word is now literary or old-fashioned | Alice could be described as Bob's paramour, but not his metamour |
| Polycule | The wider network of people connected through romantic, sexual, or sometimes intimate relationships | All three people form a small polycule |
| Telemour | An uncommon, informal term sometimes used for someone one step farther away, such as a metamour's other partner | If Charlie also dates Dana, some people might call Dana Bob's telemour |
Unlike metamour, paramour refers to a direct lover, often with an old-fashioned implication that the lovers are not married; see the Cambridge definition of paramour. A polycule is the whole connected network rather than one person's relationship to another. The UC Davis LGBTQIA Resource Center similarly defines a polycule as a network of connected relationships.
Telemour is not standardized or widely used. If precision matters, “my metamour's partner” or “someone in my polycule” will usually communicate more clearly.
What Does a Metamour Relationship Look Like?
There is no required level of closeness. A metamour relationship can sit anywhere on a spectrum:
- Kitchen-table: Metamours socialize comfortably, perhaps sharing meals, celebrations, group chats, or practical support.
- Garden-party: Metamours are friendly at occasional shared events but do not build a close independent friendship.
- Parallel: Metamours keep their relationships mostly separate and may have little or no direct contact.
None is automatically more mature or more “properly poly.” The right level is the one everyone freely agrees to. Our guide to kitchen-table vs parallel polyamory explores those arrangements in more detail.
Research reflects that range. In a 2024 qualitative study of people in consensually non-monogamous relationships, participants described both difficult, time-consuming metamour interactions and beneficial ones involving friendship, practical help, information, or support. A label cannot guarantee a good relationship; conduct and compatibility still matter.
How to Build a Healthy Metamour Relationship
See a Person, Not a Rival
It is easy to compare yourself with a metamour: they seem more adventurous, have more history with your partner, or share an interest you do not. That comparison turns a whole person into a scorecard.
Your partner's connection with someone else does not make your own qualities interchangeable. If jealousy appears, identify the actual need beneath it, such as reassurance, protected time, clearer plans, or affection, and discuss that need with your partner. Our guide to dealing with jealousy in polyamory offers practical steps without pretending jealousy should never happen.
Agree on Contact Instead of Assuming It
Some metamours want coffee and a direct line of communication. Others only want enough contact to handle emergencies. Both can work.
Before exchanging numbers or arranging a group meeting, check what each person wants. A low-pressure first meeting in a neutral place is usually easier than a major holiday or an overnight trip. Nobody should have to become friends, share intimate details, or watch physical affection to prove they are comfortable with polyamory.
Protect Privacy and Information Boundaries
Decide what your shared partner may relay between relationships. Scheduling information, changes to sexual-health risk, and agreements that affect everyone may need to travel. Details about an argument, sex, trauma, or a private confidence usually require explicit permission before sharing.
The aim is informed consent without turning the hinge into a news service. Each relationship deserves privacy, but privacy should not become secrecy about matters that change another person's risk or agreements.
Avoid Triangulation
Triangulation happens when conflict gets routed through a third person: Bob complains to Alice about Charlie, Alice edits the message, and Charlie replies through Alice. Soon the hinge is carrying a distorted conversation between two adults.
For issues directly between metamours, a calm direct conversation may be best if both people consent to contact. For issues within a couple, the people in that relationship should address them. The hinge remains responsible for managing their own promises, time, and communication; one partner should not be asked to police the other.
Coordinate Without Treating Anyone as Staff
Friendly metamours can make calendars, caregiving, events, and emergencies easier. They can also become allies who care about the same person's wellbeing. But cooperation is voluntary. A metamour is not automatically a babysitter, therapist, scheduler, or relationship mediator.
Ask rather than assign: “Would you like a shared calendar?” works better than assuming everyone wants access to one another's plans.
Let Closeness Develop Organically
Some metamours become genuine friends or chosen family. Others exchange a pleasant greeting at birthdays. A few discover mutual romantic or sexual interest and become partners themselves. None of those outcomes is mandatory.
If closeness grows, protect the independent relationships within the polycule. Group time should not quietly replace one-to-one dates, and a metamour friendship should not become a place to gossip about or gang up on the shared partner.
What If You Do Not Like Your Metamour?
You do not need to like a metamour to behave respectfully. When personalities clash, a more parallel arrangement may reduce friction: limit contact, agree on basic civility at unavoidable events, and let the hinge manage their separate commitments.
Separate incompatibility from harmful behavior. “We have nothing to talk about” calls for distance, not a campaign to end the other relationship. Repeated insults, harassment, coercion, disregard for agreed sexual-health practices, or attempts to control your relationship are more serious. State the boundary and the action you will take to protect yourself; ask your partner what they will do about agreements they made.
If you feel unsafe, prioritize distance and outside support over a group conversation. Polyamory does not create an obligation to remain accessible to someone who mistreats you.
Frequently Asked Questions About Metamours
What does metamour mean?
A metamour means your partner's other partner when you are not also dating that person. It names an indirect relationship within polyamory or another consensually non-monogamous structure.
What is a “meta” in polyamory?
Meta is common shorthand for metamour. If someone says “I met my meta,” they usually mean they met their partner's other partner. Because “meta” has many meanings outside polyamory, context helps.
What is the plural of metamour?
The plural is metamours. The common shorthand plurals naturally as metas.
Is a metamour the same as a paramour?
No. A metamour is your partner's partner, whom you are not dating. A paramour is your own lover. The similar endings make the words easy to confuse, but one relationship is indirect and the other direct.
Do metamours have to meet or be friends?
No. Metamours can be close friends, polite acquaintances, or entirely parallel. Contact should be voluntary, and nobody needs to perform closeness to validate the shared relationship.
Can a spouse's boyfriend or girlfriend be a metamour?
Yes. If your spouse dates another person with everyone's knowledge and consent, that partner is your metamour if you are not dating them too. The same term applies regardless of anyone's gender or marital status.
Can metamours date each other?
Yes, if both people independently want that relationship. Once they date each other, they are also direct partners, and the original V may become a triangle or triad. Being metamours never creates an expectation of romantic or sexual involvement.
Is a metamour an affair partner?
Not in the usual polyamorous sense. The term assumes the relationships are known and consensual. If someone has a secret affair, calling the third person a metamour can blur the crucial difference between consensual non-monogamy and deception.
Metamour is a useful word because it recognizes a real connection without dictating what that connection must become. Start with the plain definition, “your partner's partner,” then let consent, boundaries, and actual compatibility determine the relationship.
