What Is Mercury In Astrology


Mercury is the planet of intelligence and communication style. It governs our rational and intellectual faculties, perception and reason, memory, speaking, and writing.

Mercury reflects your capacity to collect, sort, and communicate the knowledge you gain through your experiences and your senses. It reflects the way you see, hear, understand, and process information and its the logical and vocal filter for our sun sign and moon sign.

Mercury rules two signs: chatty Gemini and analytical Virgo. Gemini is the yang, or masculine, the outward expression of Mercury;  Virgo is the yin, or feminine side and the analytical aspect of Mercury. 

Mercury doesn’t just rule communication. It also represents coordination. Thought processes, small talk, ideas, and sensory information from both conscious and unconscious sources all need to be coordinated and understood. Mercury analyses, sorts, groups, and makes sense of things. How do we express and convey our thoughts?

Mercury also has to do with transportation and short trips, and the nervous system.  This also is the ruler of the infamous ‘mercury retrogrades’.

The positive manifestations of Mercury include clever speech, eloquence, persuasiveness, success with public speaking and a sharp, quick mind.

The more negative manifestations include restlessness, a tendency to be critical, sarcastic, argumentative and sly.

Mercury in Pisces

Mercury (to communicate) in Pisces (Impressionable and Inspirational)

If you have Mercury in Pisces, you, your thoughts, and your ways of communicating tend to be idealistic, psychic, intuitive, imaginative, sympathetic, diplomatic, extremely sensitive, compassionate, and visionary.

This just validates your gut instincts and intuition over again.
