Enneagram Wing
The type adjacent to your primary Enneagram type that also shapes your personality, without changing your core type.
On the Enneagram diagram, each type sits next to two others. Most frameworks say people also carry traits from one of those two neighbors, their "wing." A Type 4 might lean toward a 3-wing or a 5-wing, for example.
A wing adds shading to a personality, not a second type: your core motivation still comes from your primary type.
