Systemic genogram on parchment with sepia symbols connected by lines: the visual language of the family system.
Family system symbology

The visual language of the genogram

Each square, each circle, each line tells a story. Learn to read the silent map of your family system.

Before any deep Family Constellations session, there is a visual step that changes everything: drawing the system. The genogram is the standardized map that family psychology has used for four decades to represent three generations of bonds —and the Hellingerian systemic symbols are the reading layer I apply on top to reveal what the clan does not name.

This page brings together the 15 key elements of the visual language of the systemic genogram, from the basic squares and circles to specific conventions such as the ordinal place rule of the lost child —one of the tools with the greatest immediate clinical impact in my practice—.

All content is available for online reading only. If any of the terms resonate with your story, each card includes a definition, a clinical example, and verifiable references.
