How does Mercury rule Gemini?
What does it mean for Mercury to rule Gemini?
Mercury — which oversees not only communication, transportation, and technology but also how we express ourselves and take in information — is the ruler of Gemini, the third sign of the zodiac. In other words, when it moves through the sign of the Twins, it's right at home, or in its domal dignity.
How is Mercury affecting Gemini?
Gemini (May 21-June 20) When it first kicks off its retrograde, from May 10 to 22, Mercury will be moving backward through your sign, Gemini. Being that it's also your ruler, you might feel a bit slowed-down and off-track, especially in terms of making headway on personal aspirations.
