Mercury signs: how you think and talk
Mercury shows how your mind works: how you think, speak, learn, write, decide and connect with the people around you.
What your Mercury sign means
Mercury is the messenger. Your Mercury sign describes your thinking style and your communication style: whether you speak fast or carefully, learn by doing or by reading, decide with logic or with gut feeling.
Mercury always stays close to the Sun, so it is in your Sun sign or the sign just before or after it. Knowing it helps you study better, argue less and understand why some people seem to speak a different language.
How to find your Mercury sign
Mercury moves through a sign in about three weeks, but retrogrades three times a year can keep it longer. Your birth date is usually enough; check your birth time if Mercury changed sign near your birthday.
