What is a Mercury Sign?

Mercury (or Hermes in Greek mythology) is the messenger of the gods, and the planet rules communication, intelligence, and how we think and process information. Mercury brings out our ideas, and makes connections on how we accomplish things. Knowing your Mercury sign will give you insight on the way you think, write, speak, learn, and understand. "What style of communication do we use? How do we make decisions? How do we pick up, process, absorb, and exchange information? These questions are answered, in part, by Mercury’s placement by sign of the zodiac". Mercury is how we reach our ultimate wisdom and understanding. Mercury stays in a sign about 14-30 days, depending on the sign. Many people of the same sun sign have different mercury placements because of this.
