Dyad — a relationship between two people, the simplest and most common form of partnered connection.
What it means
The term comes from sociology and psychology, where a dyad is any pair of interacting people — not necessarily romantic partners. In the context of relationships, a dyad is the classic couple, whether monogamous or one of the connections within a larger network. In non-monogamy, several dyads can combine into a complex relationship structure, but the dyad itself remains its basic building block. Seeing relationships as a set of dyads helps you notice that each pair within a network has its own dynamic, its own agreements and its own pace. It is a useful lens when you need to break a complex configuration down into understandable parts.
Example
Two people who are dating each other form a dyad. If a third person later joins them as an equal, the relationship can become a triad, but the original bond between the first two still remains a separate dyad.
