What the 3rd House Means

The house system can represent the development of a soul through life. When looking at the 3rd House in this way, it symbolizes the toddler stage when you begin to pull away a bit from your parents and explore what is around you.

Curiosity pushes you, little by little, out of your comfort zone to learn more about the world. Every person does this, but the way in which they go about it, their feelings and tendencies when interacting with people and things outside themselves, is defined by the signs, planets, and aspects of the 3rd House.

The habits described in your 3rd House may begin in toddlerhood, but the themes of this house may continue for your entire life.

The 3rd House describes:

  • your early schooling
  • how you communicate
  • the way in which you think
  • your relationship with siblings or other close but non-parental relatives
  • how you interact with your neighbors
  • your “normal,” day-to-day travel or short trips

All of these parts of your life are detailed in your 3rd House, and I will go into more detail about each one below.

Early schooling

The territory of the 3rd House covers gathering information and data. This house can offer insight as to what type of experience you had in your preschool through elementary years.

How you perceived this first taste of education, and also how the education system received you can be found within this house.

An example of this could be if you find Aquarius on the cusp of your 3rd house, or if Uranus resides there, you may have felt as though your personality didn’t match well with the type of school you attended. Your learning style may have just been too unique and more than your school could handle, even though you may be incredibly bright.

Find Capricorn or Saturn in your 3rd House? You may have worked hard and even been successful, but you may have put a lot of time and effort into school. It may have felt like a grind, but out of a sense of duty and responsibility, you felt as though pushing yourself academically was the only option.

The sign and any planets that sit in your 3rd House will help describe your first experiences with school.

The way in which you speak and hear others is detailed in your 3rd House. Your communication style, attitude toward interacting with others, and your predisposition to “hear what you want to hear” in life are all found in this house.


Aquarius or Neptune in your 3rd House, for example, could leave you rather shy in conversation and unsure about whether or not you will say the right thing.

With Aries or Mars in your 3rd, the opposite could be true and you could be quite confident when communicating and feel as though what you have to add to a discussion is valuable and deserves to be heard.

But, speaking is only half the battle when it comes to communication, and listening is just as important. We don’t all listen in the same way and this is also laid out for you in the 3rd House.

The way in which we 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. And, the way we perceive what we take in affects how we respond to it. This acts as a feedback loop and the way yours operates is described in 3rd House.

For instance, if you find Jupiter or Sagittarius in your 3rd House, when people speak to you, you may find what they have to say and their point of view to be very interesting. You may be warm and enthusiastic in your communication style and have the impression that the person you are speaking to has good intentions. In turn, the people you are speaking to respond to you as someone who is responsive, kind, and excited to hear what they have to say.

Contrast that with the effect Pluto or Scorpio could have in your 3rd House. You may be more skeptical of what others say and wonder what the real story is when someone is speaking to you. There is also the potential that it is hard for you to “put on a happy face” in a conversation or act like someone you are not just to fit in with the social setting. Because of this, it may put off certain people who care about social niceties, but, it may bring you people who are more “real” that you can enjoy a conversation with.

No sign or planet brings anything “bad” to your 3rd House and how you communicate with others. Each simply brings different strengths and challenges.

How you think

The way your mind operates is another part of your life that is described in the 3rd House. To be specific, the left side of your brain handles language, reasoning, and analytical thinking.

Everyone’s brain operates a little differently, and the sign and planets that sit in your 3rd House can offer clues as to how yours functions.

If you find Libra in your 3rd House, your mind may always be seeking balance. You may always be asking yourself how the things you say or the information you take in will affect both yourself and others.

Earthy Virgo in your 3rd could offer you an incredible mind for details. You may be incredibly analytical and practical in the way you think.

Jupiter in your 3rd House may lend you the gift of brainstorming. One thought or idea may lead to another, then another, and then an entire network of thoughts and possibilities.

Every style of thinking is unique and needed to keep balance in this world, and the details of your style can be investigated in the 3rd House.

Relationship with siblings

The type of connection you have with your siblings or other family members, besides your parents, that you are close with is detailed in the 3rd House of your natal chart.

Whatever sign is on the cusp of your 3rd House could lend some insight as to the type of relationship you have with them, and any planets that sit in the 3rd House will also add influence.

If Libra or Taurus is on the cusp on your 3rd House, or if you find Venus there, you may have a very harmonious relationship with your siblings. Maintaining a respectful connection with them may be important to you.

Find Scorpio in your 3rd? This may signal a more brooding and moody relationship, either coming from your end or from a sibling. There could also be power struggles from time to time.

Do Aries or Mars reside in your 3rd House? Sibling rivalry or competition may play a role in your relationship.

Interaction with your neighbors

Following the 3rd House’s theme of people and places that are familiar to you, we come to your neighbors.

Some people love fostering their neighborly relationships and others prefer to keep to themselves. Clues to your feelings about interacting with familiar community members may be found in the signs and planets of this house.

If you find Virgo or Capricorn in your 3rd House, you may make a great neighbor because of your desire to be helpful or out of a sense of duty.

Gemini in your 3rd House? Making small talk with the people you live near may be a part of your every day. You may love hanging around on the stoop, at the block party, or anywhere else your neighbors may gather because it gives you another chance to chat.

Short trips

One last area of life I will mention in this article that the 3rd House covers are often referred to as “short-range travel” or “short journeys.” I think of this as places you go that are either routine in your day-to-day life, such as the grocery store, or any places that you travel to that don’t feel “foreign,” where the customs and social norms are the same as what you are accustomed to, such as somewhere in your own region or country.

If Neptune or Pisces sits in your 3rd House, everyday chores may often involve some sort of mishap or confusion. Maybe you drove 2 hours to a store only to realize that they aren’t open that day. Perhaps you forgot where you were going, or got an address wrong and ended up driving around the same block 5 times only to realize that you were on the wrong side of town. Neptune or Pisces in your 3rd House could make errands an adventure!

Find Leo in your 3rd House? Perhaps you love to get out of the house every day because you see it as a chance to see and be seen. Sure, errands can be dull, but you may like to liven it up by seeing it as a chance to let your community see the real you shine. Even if it is just at the post office.

What does the sign in your 3rd House mean?

The sign that sits on the cusp of your 3rd House will add character to how you express yourself through communication, interact with your siblings, think, and travel about your community. Each sign will put a different spin on how you experience the 3rd House

What planet rules the 3rd house

Mercury is the ruler of the 3rd House. The themes of Mercury are similar to that of the 3rd House. Thinking, speaking and listening, and collecting data are the territory of the planet Mercury.

So, in addition to the placements and condition of your 3rd House, the placement and condition of Mercury will also help to flavor how you think, communicate, and learn.

What sign rules the 3rd House

The sign that rules the 3rd House is Gemini. Gemini is also ruled by Mercury. The goal of Gemini also aligns with the 3rd House, which is to gather as much information as it possibly can, with communication being one way it goes about that.

If you find Gemini on the cusp of your 3rd House, communication, learning, and remembering information may be something you excel at.

What if my 3rd House is empty?

Chances are, there are some or maybe many houses in your natal chart that have no planets in them. These are often referred to as empty houses.

So what if your 3rd House is empty, does that mean you will be terrible at communicating? Absolutely not! The absence of a planet in the 3rd House, or any house, does not mean that you can’t function well in that area of life. Actually, you may find that the territories of life covered by your empty houses don’t monopolize much of your thinking or time.

What if there are multiple planets in my 3rd House?

Three or more planets that sit within one house is referred to as a stellium. The energy from all of the planets in the 3rd House would combine and blend energies, in essence, behaving as one large, complex super-planet.

If you find multiple planets, a stellium, in your 3rd House, this means that the areas of life covered in this house such as communication or your relationships with siblings will play an even larger role throughout your life. The themes of the 3rd House may play again over and over in your lifetime and will be of more significance than other houses may be.

Hopefully, you learned much more about the meaning of the 3rd House and how it could play out in your life. But, just to throw a little more information at you, below is a table to reference to see 3rd House information at a glance!
