How Does Zodiac Love Compatibility Work?
According to astrology, zodiac love compatibility analyzes the fundamental elemental synergies (Fire, Earth, Air, Water) and quadruplicity modalities (Cardinal, Fixed, Mutable) between two sun signs. Complementary elements (such as Fire with Air, or Earth with Water) naturally harmonize, while same-element pairings create intuitive understanding.
