The 3rd House is often called the House of Communication. It defines how you take in perceptions, store and retrieve those ideas, and share and trade them with other people.

Third House matters also include close family relationships such as siblings, cousins, and aunts and uncles (your parents aren’t described in this house), neighbors, and also short, non-foreign trips.

What Does it Mean to Have a 3rd House Stellium?

Every house in your chart can be a catalyst for personal growth, but with a 3rd House stellium, this means that your 3rd House could be extra pivotal in your life.

Your stellium may intensify the matters of your 3rd House, magnifying them or making them more of a constant in your life. Some of the parts of life detailed in the 3rd House include:

  • Rational thinking
  • Your memory
  • The way in which you speak, write or use body language
  • Listening to others
  • Familiar people such as siblings and neighbors
  • Trips in familiar-feeling places

With a 3rd House stellium and the potential for the matters of your 3rd House being heightened, there are some pitfalls to watch for, however, including:

  • Talking too much or too little
  • Interrupting frequently
  • Misinterpreting what people say or how they say it
  • Detaching from emotion and only relying on logic
  • Trouble getting your message across
  • Difficult family or neighborly relationships

Of course, these will be dependent upon the planets in your 3rd House stellium and factors in the rest of your birth chart.

You may or may not struggle with any of the challenges above, but with a stellium in your 3rd House of Communication, these could be things you “check in with yourself” about from time to time and reflect on.
