Gemini is the third sign of the zodiac, ruled by Mercury, representing communication, adaptability, and duality.
Definition
Gemini is the mutable air sign of the zodiac, ruled by Mercury. It spans 60°–90° of the zodiac and is associated with the late spring season in the Northern Hemisphere. Symbolized by the Twins, Gemini reflects themes of duality, versatility, and intellectual curiosity. As an air sign, it is concerned with ideas, communication, and social interaction. Its mutable modality makes it adaptable and changeable, often excelling in multitasking and learning new skills. Gemini is known for its quick wit, restlessness, and capacity to see multiple perspectives. In traditional astrology, Mercury’s rulership ties Gemini to eloquence, commerce, and logic. Challenges can include distraction, inconsistency, and superficiality when not grounded.
In a chart
In a natal chart, Gemini is identified by planets or points located between 60° and 90° of the zodiac. Look for the house ruled by Gemini’s cusp to understand where communication, adaptability, and duality manifest in the native’s life. Pay attention to Mercury’s condition, as it influences how Gemini traits are expressed. Avoid assuming all Geminis are extroverted; other chart factors like Saturn aspects or house placements can modify this.
