Frequently asked questions
What does my Mercury sign mean?
Your Mercury sign shows how your mind works: how you think, speak, learn, and exchange ideas. It colors your communication style, from blunt and quick to careful and considered.
Can my Mercury sign be different from my sun sign?
Mercury is never more than one sign away from the Sun, so it is either in your sun sign or an adjacent one. When it differs, it adds a distinct flavor to how you express your core identity.
What does Mercury retrograde have to do with my Mercury sign?
If Mercury was retrograde at your birth, it does not change your Mercury sign, but it can make your thinking more internal, reflective, and original. A full chart will show whether your Mercury is retrograde.
