Frequently Asked Questions

What is an astrology glossary?
An astrology glossary is a comprehensive reference that defines the specialized terminology used in astrological practice. It covers zodiac signs, planets, houses, aspects, chart types, and advanced concepts like dignity, decan, and sect, helping beginners and experienced practitioners alike communicate clearly about astrological topics.
How many terms does astrology use?
Professional astrology uses hundreds of technical terms. This glossary covers over 80 of the most essential terms, including all 12 zodiac signs, 10 planets, 12 houses, 6 major aspects, 7 chart types, and dozens of key concepts like retrograde, stellium, and chart ruler.
What is the difference between a sign, a planet, and a house?
In astrology, planets represent fundamental drives (what energy), signs describe how those drives express themselves (how the energy manifests), and houses indicate where in life the energy plays out (which life area). For example, Venus (love) in Scorpio (intensely) in the 7th house (partnerships) describes someone who loves deeply and passionately in close relationships.
Do I need to know all these terms to read a birth chart?
No. Start with the basics: the 12 zodiac signs, the 10 planets, and the concept of houses. As you gain experience, you can explore more advanced terms like aspects, dignities, and chart patterns. This glossary is organized alphabetically so you can look up terms as you encounter them.
