The Meaning of the 3rd House in Astrology

In astrology, the 3rd House is often called the House of Communication.

While this is your natal chart’s center for speaking and listening, there is more to it than that.

Your 3rd House also helps to shape how you learn and think.

Beyond that, some familiar territory is also a part of this house.

People like siblings, cousins, and even neighbors are included. Local or regional travel and moving about your neighborhood are also described in your 3rd House.

  • Speaking
  • Writing
  • Listening
  • Transportation
  • Short-range travel
  • Learning and early education
  • Siblings and cousins
  • Neighbors
  • Perceiving and gathering knowledge
  • Thinking
  • Memory

The 3rd House Rules How You Communicate

Your communication style is detailed in your 3rd House.

This includes how you get your point across to others.

It also details how you may feel about communicating and what you like to talk about.

Is it details and facts that you love to share with others or new and innovative ideas, or is it emotions or even taboo topics that you find yourself talking about?

Where and how you like to talk also falls into the territory of the 3rd House.

Do you prefer to speak with only small groups of people that you already know and trust, or does public speaking light you up?

But, speaking is only half the battle when it comes to communication, and listening is just as important.

The way in which we take in and perceive information we take in is different for each of us.

Everyone has a unique “filter” that they listen through that colors that information in a certain way. The phrase “you hear what you want to hear” fits this perfectly.

And, what we hear affects how we respond to it.

This is like a feedback loop as you hear what you want to hear, respond accordingly, and then those around you react to it in a way that fulfills what you “heard.”

Your 3rd House helps to describe what kind of “loop” you may find yourself in when it comes to listening and responding.

The 3rd House Rules How You Think

The way your mind operates is another part of your life that is described in the 3rd House.

More specifically, it rules the part of your mind that handles language, reasoning, and analytical thinking.

Your 3rd House is all about perception and how you pull in, categorize, and later share knowledge and what you have observed.

Everyone’s mind operates differently, and your 3rd House may offer clues as to the style in which your mind takes in information and your memory.

The 3rd House Rules Early Education

Along with how you think, the 3rd House represents how you were taught.

This doesn’t include college, which is more 9th House territory, but rather earlier schooling experiences.

The condition of your 3rd may offer insight as to what your early learning style was.

And, it could shed light on how you experienced your education.

Was this a learning environment where expressing feelings and imagination was encouraged or were your instructors strict taskmasters who thought children should be seen and not heard?

The 3rd House Represents Your Siblings

Sibling relationships are covered in this house, as are your connections to non-parental relatives like cousins.

The dynamics of how you interact with or view your brothers and sisters can be shaped by the condition of your 3rd House.

Do you cherish every moment you get with your siblings, or does it always seem to be a power struggle? Is there the feeling that you depend on each other for emotional support, or have you never really felt like you fit in with them?

Some of the particulars when it comes to how you are tied to your brothers and sisters fall into 3rd House territory.

The 3rd House Rules Neighbors and Travel

Your local environment is another part of life detailed in the 3rd House.

The style in which you move about in your area or region is laid out here. This is travel that doesn’t seem foreign where the customs and way of life seem familiar to you.

Perhaps you are someone that has to get out of the house every day to see and be seen, or maybe you dread leaving your comfort zone to deal with public transportation.

Clues as to how you feel about traveling in your city or neighborhood can be found in your 3rd.

But, you can also gain insight into how you experience this type of travel.

Maybe it seems like the world is your oyster when you step out of your house with green lights popping up just before you hit the intersection and each line you choose when checking out is the fast one.

Or, it could be that you have the opposite experience where every time you run errands it feels like a grind full of long lines, car trouble, and puddles you didn’t see until it was too late.

These are both 3rd House experiences.

Beyond traveling about in your region, familiar faces in your neighborhood, such as neighbors, and your interactions with them are also covered in your 3rd House.
