The twelve mercury signs at their best -

Mercury in astrology represents our logical mind, whereas the moon represents our emotional mind. Mercury is the part of us that is always taking information in so we can analyze it and make output out of it eventually. It is who we are when we are at work, making lists and running errands. The Mercury sign represents the way that someone goes about doing these things that are very closely connected to our material world and the traits connected with them. It also rules over communication and the way that we speak, write and communicate.
