Astrology Glossary: Key Terms Explained

Astrology has its own vocabulary, and it can get confusing fast — especially since Vedic and Western astrology often use completely different words for related ideas. This glossary collects every key term used across our guides in one place, organized by category, so you can quickly look up an unfamiliar word without losing your place in whatever you were reading.

Key Takeaways

  • •This glossary covers terms from both Vedic astrology (Jyotish) and Western astrology, since the two traditions often use different words for related concepts.
  • •Terms are grouped by category — Charts & Placements, Vedic-Specific, Western-Specific, and Reports & Doshas — so you can scan the section most relevant to what you're reading.
  • •Many terms link directly to their full guide, so you can go from a quick definition to a deeper explanation in one click.
  • •If you came here from a specific report or article and a term wasn't fully clear, this is the fastest way to look it up without leaving the site.

Frequently Asked Questions

Why do Vedic and Western astrology use different terms for similar ideas?▼

The two traditions developed largely independently — Vedic astrology from Jyotish Shastra in India, Western astrology from Babylonian and Hellenistic Greek tradition — so even closely related concepts (like Rashi and sun sign) carry distinct vocabulary and calculation methods.

What's the single most important term to understand first?▼

Birth chart (or Kundli in Vedic terms) is the foundation everything else builds on — nearly every other term describes a specific piece of that same chart.

Is this glossary complete?▼

It covers the terms used across our current guides; if you come across an unfamiliar word in a specific article that isn't listed here, the article itself will typically define it in context.

Can I use Ctrl+F / Cmd+F to search this page?▼

Yes — since terms are organized alphabetically within each category, a browser search for a specific word is often the fastest way to find what you're looking for.
