This glossary isn’t a comprehensive, inviolable catch-all for every single word and term used within polyamory communities! In our increasingly inter-connected, globalised world, language is constantly changing and evolving, and it’s not possible for a term to be described in a way that resonates with each person’s experience—particularly in an area as deeply personal as sexuality.

Polyamory — like monogamy! — is diverse, and encompasses people and practices from diverse communities with their own substantial glossaries, such as the LGBTQ, swingers and BDSM communities (for which you can find excellent comprehensive glossaries on-line) and we simply couldn’t put every term in.

We’ve stayed away from terms that are too academic, too boring, too judgmental, too wild, or that relate mainly to religion. Let us know if there’s an important word you think we’ve missed and we’ll add it!
