Like the our sun, moon, and rising signs, we also have a Mercury sign! As mentioned above, our mercury sign gives us insight into our intellect and communications. Depending on the sign our Mercury is in, as well as the house, and aspects to the planet, we may or may not be great speakers or communicators.
Symbolically, water is our emotions. Air is our thoughts. An air sign, or someone who has a lot of air in their chart, will usually rationalize their emotions. This is the reason that passivity happens among air signs. While it is great to be considerate of others people’s feelings, we must also feel our own feelings and allow them room for expression; otherwise, instead of feeling them, we only think about them. This can cause a buildup of unsaid words left inside of us.
