As promised, here is a (hopefully) comprehensive guide to some common polyamory terms. These are all my own personal definitions, so bear in mind that others may use these words in different contexts :) If I missed anything, please add it in the comments!
Note: not in alphabetical order because that’s too logical for me.
Polyamory/poly- see this post.
Monogamy- a more socially accepted relationship model involving two people who are exclusive to each other. Works for some people, doesn’t work for others.
Non-monogamy- an umbrella term which, as the name implies, encompasses everything that is not monogamy. Things that come under this category include polyamory, swinging and cheating.
Open relationship- a polyamorus relationship where the people involved seek, or are open to the idea of, more people becoming part of the group.
Closed relationship/polyfidelity- a polyamorus relationship where the people involved are in exclusive relationships and are not seeking, or open to the idea of, any more people joining their relationship.
Group marriage- a polyamorus relationship where the people involved make life commitments to one another (like ‘normal’ marriage, but with more than two people).
Primary/secondary- two different types of relationships within polyamory. A primary group/couple may be more committed, and share responsibilities and benefits such as child raising, pooling finances and living together. A secondary relationship is usually more casual.
Triad- a polyamorus group of three people.
Quad- a polyamorus group of four people.
Network- a polyamorus group involving more than four people.
Triangle/delta- a triad relationship model where all three members are involved with each other. As such, the connections between the members of the group form a triangle/delta shape.
Vee/V- A triad relationship model where one person is involved with two others. Think of the letter V as a triangle with one less connection.
N- A quad relationship model. Think of a V model but with an extra connection.
Hinge- a person who is dating two or more others, and thus becomes a ‘hinge’ between those people. A V relationship has one hinge in the middle, an N has two and so on. A network may have many hinges connecting the group together.
Metamour/spouse-in-law- two or more people who share the same partner, but are not involved with one another. The two people at either end of a V relationship are an example of this.
Compersion- an emotion that is the opposite to jealousy. It is the feeling of positive empathy when you see someone else happy. In the context of polyamory, compersion is the warm, fuzzy feeling you get when you see your partner enjoying other relationships.
New Relationship Energy (NRE)- The excitement and happiness you feel when a new relationship begins. In polyamory, this energy often reignites the excitement in old/existing relationships.
Spice- the plural term for spouse. Eg. “My spice and I are going out tonight”.
Polygamy/polygny/polyandry- these terms have little to do with the polyamory movement and are more commonly used when referring to people who are non-monogamous for religious or cultural reasons.
My next post (or at least a post in the near future) will focus on my two partners and I, and use these definitions to explain our relationship and dynamics.
