In Astrology, Mercury represents communication, while Uranus represents unpredictability, originality, and independence.
When your Mercury conjuncts your partner’s Uranus, communication figures strongly into your relationship. The Uranus person enlivens the Mercury person’s thoughts and ideas, and opens Mercury’s mind to a wide spectrum of intellectual possibilities. Indeed, Uranus challenges Mercury’s way of thinking. Mercury finds Uranus highly exciting and original, while Uranus loves sharing ideas with Mercury. The two of you enjoy experimenting with new ideas. The two of you may be prone to making impulsive, hasty decisions together.
Hard Aspects (square, opposition) between Mercury and Uranus in synastry indicate lively, stimulating conversation. Indeed, Uranus stimulates Mercury’s mind. However, there can be differences of opinions on key issues. The Uranus person may find the Mercury person overly analytical or boring, while the Mercury person is likely to see the Uranus person’s ideas as zany and radical. The Mercury person may find it difficult to depend on the Uranus person to meet for dates. The two of you may be prone to making impulsive decisions.
The harmonious aspects (sextile, trine) between Mercury and Uranus in syanstry are much easier to handle. In this case, Uranus enlivens Mercury’s ideas, and opens Mercury’s mind to an array of intellectual viewpoints. You are very perceptive with one another. Communication figures strongly into your relationship.
