A reference glossary of 47 astrology terms, written for technical accuracy and interpretive clarity. Covers the astronomy underneath the chart, the anatomy of the chart itself, the planets and their motion, the aspects between them, and the foundational concepts that hold it all together.
This glossary is the reference layer of ZODIA. Every definition is grounded in the actual astronomical or astrological mechanics being described, with the interpretation built on top rather than substituted for the technical content. If you have ever wanted to know what an ephemeris actually is, or how a rising sign is calculated, or why squares are different from oppositions, you are in the right place.
Terms are organized by category. Within each category, related terms cross-link to one another so you can follow a concept from its definition to its connections.
