Mercury is small, fast, and lives close to the Sun. In your chart, it is the part of you that observes, sorts, names and explains.
Mercury by element
Fire-sign Mercury thinks in flashes — quick conclusions, big claims. Earth-sign Mercury wants evidence and examples; it is slow but rarely wrong. Air-sign Mercury thinks in words and connections; it can outrun its own conclusions. Water-sign Mercury thinks in images and feelings; logic comes second to intuition.
Mercury by house
The house of Mercury shows where your mind is busiest. 3rd house: siblings, neighbours, daily errands. 9th: long study, philosophy, travel. 6th: the language of work and health.
Mercury retrograde
About three times a year Mercury appears to go backward. It is a famous time for miscommunication and re-thinking. See the full Mercury retrograde guide.
Look up your Mercury in your natal chart and read it together with the Sun — together they describe your inner monologue.
