The astrology glossary
The words of the craft, one per page: what they mean, how to spot them on your chart wheel, and what they change in its reading.
Patterns
When three or more planets draw a shape on the wheel.
- Grand trineA grand trine links three planets set roughly 120° apart: each one forms a trine with the other two, and their lines draw a triangle in the middle of the wheel.
- T-squareA T-square appears when two planets face each other in opposition and a third sits halfway between them, square to both.
- Grand crossA grand cross links four planets stationed at the four corners of the zodiac: two oppositions crossing each other, and four squares joining their ends.
Reading aspects
The allowed gap, the motion, the lesser-known angles.
- OrbThe orb is the leeway given to an aspect around its exact angle.
- Applying and separating aspectsAn aspect is applying when the faster planet is moving toward the exact angle: the gap is closing.
- QuincunxThe quincunx, also known as the inconjunct, is the 150° aspect: two planets five signs apart, nearly opposite but not quite.
The great families
Every planet, sign, house and aspect has its own page too.
