The Third House, ruled by Gemini, contains your siblings, education, communication, transportation, and self-expression. It helps you to open your mind to a variety of new ideas, then to mold those thoughts into a form that can be expressed in the world. The third house represents ideas and metal acuity. It provides hints about how you speak and how you learn.
Read the sign on the cusp of your third house to provide information about how you get your ideas across to the world. For example, a Cancer third house cusp may speak in words that express feelings and emotions, whereas a Sagittarius cusp may speak in broad, altruistic, and philosophical concepts.
The third house also represents communication and travel that happen quickly, such as a one-day workshop, writing a magazine article, or taking a short weekend trip.
The third house can also tell you about your brothers and sisters, since they’re how you learned to communicate in the first place. It can also give you hints about the car you drive: a Leo third house cusp, for example, may want to drive a showy luxury car!
This is one of the places in the chart to look at the nervous system, respiratory ailments, asthma, and communications problems like stuttering.
