The Astrology Glossary

Every term, defined plainly — from aspects and orbs to profections, declinations, and lots more obscure than that.

This glossary is the working vocabulary of the Astrologer app. Definitions are written for people who want to actually understand astrology, not just read horoscopes. Click any term to read its full definition and see how it shows up in a real chart.
