What does Mercury represent?
Mercury was the messenger of the gods — the agile figure running between worlds, carrying messages. In astrology, too, it is the go-between: it turns thought into speech, perception into understanding. It always travels close to the Sun and never strays far.
Meaning in the chart
Mercury represents how you think, speak, and process information. It is the planet of ideas, words, and learning.
The sign it is in shows your style of communication and thinking, and the house it is in shows the area of life your mind is most occupied with. When Mercury is retrograde, the mind works inward rather than outward.
