Synastry (from Greek syn, meaning "together," and astron, meaning "star") is a term used in astrology to describe the study of the interactions between zodiac signs of two or more individuals. It involves comparing and analyzing the natal charts of different people to determine the strengths and challenges in their relationships. Synastry is often used to assess romantic compatibility, but it can also be applied to friendships, family dynamics, and professional partnerships. In Hebrew, the term is translated as סינסטרי (sinastri). In French, it is known as synastrie, and in Spanish, it is referred to as sinastría. Key aspects of synastry include examining the positions of the Sun, Moon, and planets in each individual's chart, as well as the aspects (angular relationships) between these points. Astrologers use synastry to gain insights into the emotional, intellectual, and physical dynamics between people, helping them understand the potential for harmony or conflict in their relationships.
