Mercury
Mercury governs the mind and communication.
Mercury governs the mind and communication. It represents thinking, speech, learning, and the way a person gathers information and passes it along. Mercury is how someone makes sense of things and reaches others through words and ideas. It rules two signs, Gemini and Virgo, and never strays far from the Sun, so it always falls in the Sun's sign or one beside it.
By sign, Mercury shapes the style of thought and speech, quick or careful, playful or exact. By house, it shows the part of life a person turns over in their mind and returns to in conversation. A strong Mercury brings clear thinking, ready expression, and lively curiosity.
When Mercury is strained, communication grows anxious, scattered, or prone to being misread. Mercury also rules short journeys, daily errands, and the handling of small practical details. Its work is honest and clear communication, learning to think well and to shape thought into words that others can actually follow.
