Like every other discipline, astrology has its own glossary, a set of specific terms that refer to the many aspects of this ancient art. These are the most common terms used by astrologers.

It goes without saying that there are a great many zodiac terms and phrases that we haven’t included here. If you feel there are any missing that are of particular importance, please use the comments form at the bottom of this blog post to let us know all about them. We’ll be more than happy to expand this glossary over the coming weeks and would be delighted to have your valuable input.
