Polycule

What is a polycule?

Polycule is the word for the interconnected network of people who are linked to each other through polyamorous relationships. It’s a blend of poly and molecule, because the diagram of such a network can look like the schematic of a molecule. A polycule can refer to the people themselves or to the diagram that maps their mutual bonds.

What a polycule looks like

A polycule is best drawn. Take a woman with two partners. If one of those partners also has a girlfriend of their own, the polycule is four people, even though not everyone knows each other equally well. Ready for Polyamory describes a polycule as a network of interconnected relationships, and as the drawing that maps that same network. The lines in such a diagram are the relationships. The people at the end of a line who have no relationship with each other are each other’s metamours, that is, their partner’s partners. In that example, the woman’s two partners are each other’s metamour, and one partner’s girlfriend is a metamour of the woman. Four people, three relationships, and everyone is still in the same polycule. It can start that small, and grow that big.

How a polycule fits together

The shape of a polycule says something about how it works. A triangle in which all three people have a relationship is called a triad; four people together, a quad. More often it’s a vee, in which one person has two partners who aren’t a couple themselves. Wikipedia defines a metamour as someone who is the lover of your lover without your having a romantic bond with that person yourself, and it’s exactly those metamour connections that decide how close or how loose a polycule feels. Within the same polycule, one branch can be in each other’s pockets and another barely know each other. Larger networks sometimes get their own name or a group chat, and drawing the polycule is, for some people, a handy way to keep track when partners, metamours, and their partners keep branching out. The shape is never fixed: a polycule grows when relationships are added and shrinks when relationships end.

Why the word polycule is useful

The appeal of the word is in the overview. Once relationships branch out, it gets hard to say in plain language who belongs with whom, and “my polycule” catches that web in one word. For you it makes it possible to talk about everyone who plays a part in your life, including the people you don’t date yourself but do run into. Consensual non-monogamy is by now a seriously researched field: the review by Gupta and colleagues brought together 209 studies and shows that such networks are a real and varied phenomenon. What the word doesn’t solve: drawing a polycule doesn’t make the agreements inside it clear by itself. That stays communication work. A pretty diagram says nothing about how it actually runs between the people on it. Knowing your polycule doesn’t automatically tell you how everyone feels about each other; that stays something to talk through, not something to read off. The word gives you a peg, not ready-made agreements.

What a polycule is not

“In a polycule everyone has something going with everyone.” No. A polycule is the network, not one group relationship. Many people in it are each other’s metamours and have no relationship themselves.

“A polycule is a closed little club.” Not necessarily. Some polycules are closed (see polyfidelity), others are open to new relationships, which is how the network grows and shrinks.

“You choose your whole polycule yourself.” Partly. You choose your own partners, but not who they in turn get involved with. So part of your polycule comes about without you.

What you can arrange yourself

A polycule runs more smoothly with a few agreements.

• Map your polycule when it gets hard to follow. A simple drawing makes clear who belongs with whom, and helps you not forget metamours in decisions that affect them.
• Agree which metamours meet. One branch wants to sit at the table together, another would rather stay separate. Name that instead of letting it happen.
• Sort out safer sex across the network. In a polycule, choices about testing and protection touch more people than just your own partner, so make concrete agreements about it.
• Talk about changes before they become a surprise. A partner’s new relationship changes your polycule too; hearing it earlier saves a shock later.

More reading on the polycule

Within this glossary, metamour explains who the people on the other side of the line are, and kitchen table polyamory and parallel polyamory show how close or how loose a polycule can be. Beyond this site, Gupta and colleagues give a level-headed overview of the research.

Where this fits on this site

Are you in a polycule and looking for a discreet date outside your network? Then that’s a question you put honestly to your circle instead of arranging on the sly. If you’d like to spar calmly first about what fits, that’s what the conversation beforehand is for, no judgment.
