In astrology, Polarity refers to the division of the twelve zodiac signs into two complementary groups. Fire and air signs are generally associated with a more outward, active, or expressive orientation, while earth and water signs are associated with a more inward, receptive, or responsive orientation. Older astrological sources may describe these groupings using terms such as positive and negative or masculine and feminine. Polarity is one of several structural ways of organizing the zodiac and can be considered alongside elements and modalities when examining broader patterns within a natal chart.
