Air is the realm of the mind. It invokes curiosity and brings an eagerness to make connections with other people. Air circulates ideas and thoughts, and it understands function in the world around us. Having too much Air can make a person overly chatty or too intellectual about even the simplest things in life. Not enough Air and a person may have difficulty communicating with others.
Gemini, Libra, and Aquarius are the three Air signs. Having some of Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn placed in these signs can ensure a good representation of the Air element.
