3rd House Meaning In Astrology

The Meaning Of The Third House In Astrology

In Astrology, the third house governs the mind and controls a person’s mind, communicating skills and intellect. The House is primarily about communication, exchanging words and thoughts in a carefree way. This follows the second house cusp of the body, and the third house now moves into its natural ruler, the mind.

Because the house is ruled by Gemini, it is also governed by the planet Mercury. The 3rd House is strongly linked to the dealing a lot with communication on a fundamental level.

It regulates a person’s desires, dreams and ability to deal with specific problems.

The house rules courage and will power of a person.

It has a significant impact on a person’s health and attitude and relationship with siblings and neighbours.


The third house regulates primary education (until high school) and sets the basis of knowledge, which afterwards is shown from the house that lays precisely opposite the 9th one. The house also rules the routine behaviours in the nearby society.

We’re schooled in social interaction. So here rules our early education, our relationship with a high school. Honestly, the first ten or so years of school are much more about hanging out with one’s classmates than studying this or that science.

The 3rd House rules over short distance, short journeys and short trips.

If the 3rd House changes Zodiac signs somewhere in its span, this indicates your relationship with friends and acquaintances will change somehow at some point in life. Usually, it also means changing friends.

This also means that if most or all of the House is in the same Zodiac sign, you tend to stick to the friends you got at the beginning. At least, your type of relation remains the same, even if you get other friends.

Third House in Aries

If the third house begins in Aries, we see an individual with a fast mind and an aggressive approach to communication. This is someone energised and filled with active ideas, whose mind never stops working.

This person has to learn about the consequences of their words, as well as words spoken by other people. They realise what they need to do to become real leaders, giving respect to everyone around them.

Third House in Taurus

If the third house begins in Taurus, thoughts are often static, slow and ‘activated’ by hedonistic or material matters. This placement is one of the most practical and constructive positions.

When a person born with this placement discovers their talent to create, it’ll bring them a lot of satisfaction in the material world. The greatest challenge is to accept change.

Third House in Gemini

If the third house begins in Gemini, it’s is the most natural of all positions. This person has a smart approach, clarity in their choice of words and mind.

There is an attachment to their siblings and points out that communication is an essential part of a person’s life. These individuals need a healthy routine and also to respect time, their body and to be satisfied, syncronised with and speak from their heart.

Third House in Cancer

If the third house begins in Cancer, here speaks of inherited intelligence. If someone is born into a family of educated individuals, we can safely presume that their knowledge will be similar.

The primary challenge of each Cancer thinking individual is in expressing their emotions practically. Here exists the battle of reason vs emotion even though, both should be rolled together.

Third House in Leo

If the third house begins in Leo, thoughts are mostly focused on one’s Self. In a way, these people can become the happiest of everyone once they learn to accept and nurture their child within. This is definitely a strong position that brings a lot of ego challenges. They should express their core personality with smooth and shine a light on everyone around them.

Third House in Virgo

If the third house begins in Virgo, this position is equally weakening and empowering. While Virgo exalts Mercury and speaks of intelligence but also a point of practical issues and health issues that don’t need overanalysis. They develop a strong faith and leave room for love, inspiration and creativity, without digging for rational explanations for every single thing.


Third House in Libra

If the third house begins in Libra, we can see someone who thinks and speaks of other people way too often. Here is somebody who has a strong personality and needs to be aware of their own judgment and attitudes, before discussing with others. Once they master incorporating their own opinions into society, they become great thinkers and orators.

Third House in Scorpio

If the third house begins in Scorpio, it’s not easily handled. This is a strong, deep mind, enriched with a dark sense of humour. Thoughts and words are difficult to remain pure and free of dissatisfaction.

The darkness of Scorpio means a person needs emotional clarity and enough laughter and easiness in life. The best practice for this placement is to imagine beauty daily and choose a creative line of work.

Third House in Sagittarius

If the third house begins in Sagittarius, we instantly see someone who talks a lot. These people are natural optimists, travellers and teachers.

However, they get lost, talk excessively, while thinking and talking rather than actually acting in their own best interest. Scattered opinions and expressions will quickly take over when they are tired and lost in their path through life.

Third House in Capricorn

If the third house begins in Capricorn, we can see a pretty tough individual. They shouldn’t detach from their emotions. Compassion followed by rest is the challenge of this house.

They can be incredible in-depth, practical mentors and a real inspiration for everyone around them if they do not take life too seriously.

Third House in Aquarius

If the third house begins in Aquarius, we instantly see an incredible mind filled with brilliant ideas and abundant social life.

With liberated expression and a mind turned to alternative forms of reasoning, these people make good astrologers, innovators, and friends.

Without a strong physique, one’s incredible mind needs grounding to bring its sparkling existence down to Earth in a satisfying way. 

Third House in Pisces

If the third house begins in Pisces, this is a sign of Mercury’s fall.

This can be confusing, strange, and deeply challenging for one’s ability to speak, write, or even think clearly.

This house in Pisces to reach clarity, all mind-altering substances should be avoided.

Purity within will allow the purity of mind. If they practice what they preach, they can discover that magic of life is there for the taking.
