Moon in 3rd House Synastry Meaning, Symbolism, and hidden elements to consider in zodiac compatibility analysis!

So, you are talking to someone new, or you’ve been in a relationship for a while, and you are eager to get some insight into the true potential of the relationship.

You’ve learned about the significance of house overlays and are now impatient to explore what it means to have their Moon in your 3rd House in synastry (or vice versa).

The Moon is indeed a whole mini world in astrology to deeply explore and understand, both in your own natal chart and in your compatibility analysis with another person.

In its essence, the Moon as a symbol is the embodiment of our soul with all the joys, hurts, experiences, and wisdom it carries from our past lives.

The Moon is one of the most delicate points in our natal charts, and it is also the door through which we can access the emotional world of someone else (if we know how to). Indeed, we should thread softly in this venture, for which reason I need to draw your attention to a few things before I tell you what the Moon in 3rd House Synastry may or may not mean for your relationship.

Moon in 3rd House Synastry: When does it Actually Mean Something?

To get you started with house overlays, I must first tell you that they can mislead you greatly if you haven’t taken the initial few preliminary steps in your compatibility analysis.

Most importantly, the Moon in 3rd house synastry overview I am about to give you will mean very little for your relationship if you haven’t looked at each of the charts separately beforehand.

Gaining a good understanding of each other’s needs, desires, and approach to love and relationships separately is a key step that by no means should be skipped or overlooked.

The Moon, of course plays a significant role in this initial analysis, because its position by sign, house, and aspects will give you a very thorough understanding of each other’s hidden emotional needs, inner talents, and trauma that has to be dealt with.

I like to give the example of Moon square Venus, which is a classic example of a woman, who has issues in her early relationships, because of inborn insecurities she has and the inability to truly value and appreciate herself. A woman with this aspect usually projects her emotional instability onto partners and often attracts narcissists, who further enhance this skewed self-image she has of herself. By making the wound hurt, they empower her to finally deal with the issue and start practicing more self-love and appreciation. Although early relationships may be a good catalyst for ‘forcing’ someone with this aspect to work on it and overcome it, the best kind of partner for someone with this aspect would be an individual, who has a trine between these two planets, and can assist her in the healing process.

For men, this same aspect means that they have an inner contradiction of the type of woman they want for a long-term partner. They have an inherent draw towards very different types of women, and they often find someone, who they consider as ‘wife’ material, and another one, who they consider as a ‘lover’.

This is exactly the reason why, if your partner’s Moon falls in your 3rd house in synastry, it will mean one thing if their Moon is harmoniously placed by sign and by aspects, and completely another thing if their Moon is heavily afflicted.

The One Most Important Thing To Remember About Moon in 3rd House Synastry

moon in 3rd house synastry

The most important thing to remember about having someone’s Moon in your third house in Synastry is that it acts as a permanent transit to your third house!

This means that for as long as you are in this particular relationship, for as long as you communicate and exchange energies with this person, their Moon will be like a permanent transit in your third house.

Their Moon, with all it represents will be affecting your own communication style, your thought patterns, the way you are able to connect with others, and even maybe your relationship with close relatives and friends! If you have planets in your third house, their Moon will be further activating these planets, and the aspects they are making.

Let’s say you have Mars in the third house, making a trine to Mercury. This would make you very well-spoken and assertive of yourself. You will be very confident in expressing your opinions and  making people hear your voice. You would be able to use humor and sarcasm in a smart, witty way, but the trine makes the aspect milder, so you would be able to do it without offending others. You would also most likely have a good type of relationship with a younger sibling of yours.

What would someone else’s Moon in your third house do with this aspect? Well, it will further enhance it, but also give it an emotional flair. When you are with your partner, you will not only be assertive and well-spoken, but your words will carry a certain nuance of emotion and pathos that would further captivate the listener. Your partner could help you become more imaginative and even help you warm up the relationship with your siblings. In two words – someone else’s Moon there will further enhance the positive aspect in your chart, while you are with them.

Now let’s say the trine was not a trine, but a square. In this case, you would still be very self-assertive in your communication style, but in a more rude, unrefined way. You would most possibly want to impose your opinion on others and pick fights with them if they don’t agree with you. So, now what would someone else’s Moon in your third house do to this aspect? It can make you rage! Adding the volatile, emotional nature of the Moon to a Mars-Mercury square in the third house can make one a ‘raging maniac’, mostly in the relationship – and it will all be done subconsciously.

I hope you can see why these things are critical to consider when making a proper Moon in 3rd house synastry analysis!

This is exactly the reason why it is absolutely vital that you FIRST have a very thorough and in-depth examination of their Moon in their own chart. And of course, your Moon in your own chart.

AND to know very well what the Moon symbolizes and what the Third House symbolizes.

What Zodiac Sign Am I MOST Compatible With? ‘McDonald’s’ Astrology vs The TRUTH!

One key thing to remember about the Moon when it comes to synastry is that it always shows our relationship with the mother. And this very first relationship we’ve had in our life will reflect ALL other relationships from now on. This is valid for absolutely everyone.

The Moon shows in a very expressive, almost ‘picturesque’ kind of way how our mother loved us, or more precisely – our perception of how we were loved.

And, this very first lesson on how to love is deeply ingrained in our subconscious mind, therefore, putting a mark on all of our relationships. Unless we mindfully and consciously choose to change something. This is why, when someone else’s Moon falls into our third house, they will bring this very strong ‘maternal’ energy into it, and whether this energy supports us in further developing our communication style and learning abilities, or projects disagreements and makes us more pessimistic, entirely depends on the Moon’s position by sign and aspects.

The Moon in the air signs (GeminiLibraAquarius) is very light, communicative, and adaptable. It brings with it the need to communicate and to intellectualize feelings. Air Moons bring lightness, collaboration, and curiosity with them.

The Moon in fire signs (AriesLeoSagittarius) is passionate, direct, and very dramatic. It brings with it an energy of adventure, self-assurance, and the need to be noticed, loved, and appreciated.

The Moon in water signs (CancerScorpioPisces) is nurturing, intuitive, and imaginative. It brings with it the classic feminine energy of magnetism, depth of feelings, and the inborn need for emotional attachment.

The Moon in earth signs (TaurusVirgoCapricorn) is practical, grounded, and down-to-earth. It brings with it an energy of stability, maturity, and the need to show love through practical acts of kindness.

The third house represents our communication style, the way we connect with others and the way we process information.

Since it’s a ‘communication’ house, someone else’s Moon there will definitely have a visible influence on how we connect with them, but also with others, while we are with them.

The third house speaks of how easily we approach others, pick up conversations, and the way we like to express ourselves with words.

It also reveals our thought patterns – are they mostly optimistic, or more on the pessimist side?

Do we learn easily, or we need more time to process information.

If our third house is in a water sign, someone else’s water Moon there will make us even more emotional and touchy in our communication with them and others.

The third house also speaks of short trips, our relationships with close friends, relatives neighbors – everyone that is in our closest surroundings.

As a general rule, night houses (the ones in the lower hemisphere) are not being perceived by the individual clearly and directly with their conscious mind.

Rather, they are being driven by subconscious patterns we were born with. This is why when a partner activates our third house with a planet (in this case the Moon), we can make observations and draw conclusions about our own subconscious thought patterns. This is of course possible if the individual is able to distinguish their own behavior and reactions from the influence that the partner has on them. Which is not always too easy, but not impossible if one strives for mindful self-development.

The third house rules one’s ideas about how people should approach each other and behave in relation with one another. When a partner activates this house with their Moon, the individual will react to this stimulation as if this is not their partner, but rather a relative or an acquaintance. This may seem in a way inadequate in close relationships.

On the other hand, if there are other issues in the relationship that make the partner seem like ‘an enemy’, such a position can be very beneficial, especially during conflict and confrontation. The Moon there will immediately soften the situation and contribute to a more heart-felt communication between the couple.

Learning is also part of third house symbolism, which means that when a partner’s planet falls there, they can teach you a lot about the things that the planet represents.

In the case of the Moon, this would be sensitivity, caring, and protecting each other. You just need to be open to learning from your partner!

The partner can surely have an impulse to teach you something, but the way you respond to it will entirely depend on the state of your third house and the planets placed there (as we discussed above).

Moon in 3rd House Synastry Meaning

moon in 3rd house synastry

When the Moon falls in the third house of the partner’s horoscope, they may be fascinated by the way in which the house person’s mind works and the way in which the house person tackles their mental problems.

The house person’s ideas may stimulate the Moon person’s mental reactions with favorable or unsettling results, according to the nature of the cross-aspects involving the Moon. When these cross-aspects suggest some lack of harmony, an emotional factor may intrude, which prevents accurate comprehension of the ideas each may wish to communicate.

When the cross-aspects are helpful in the Moon in 3rd house synastry connection, a useful mental rapport can be established. The Moon person may be instrumental in sowing in their partner’s mind the seeds of a new idea, which flourishes in due course. The Moon person may also quite intuitively help the house person gain sources of useful information which augment and complement their own ideas.

Should the Moon be afflicted at birth and the cross-aspects be unfavorable, there may be a tendency for the Moon person to set their partner off on a false trail of thought or they may even fail completely to have any sympathy for the house person’s ideas.

In other cases of the Moon in 3rd house synastry aspect, the Moon person can, so to speak, hold a mirror up to their partner and point out some of the flaws in their thinking, helping them as a result to communicate more effectively with others.

Such interactions may not always proceed smoothly, hence the more strenuous cross-aspects may be in evidence in such cases. Sometimes the Moon person may absorb  their partner’s ideas and later on repeat them to the house person as their own.

On a more positive level, the Moon person’s memory may often assist their partner to add useful facts to their own store of information.

With positive aspects involved in the Moon in 3rd house synastry overlay, the couple may enjoy a very smooth, intuitive style of communication with each other in which they just ‘get’ one another without words. They are able to ‘sense’ the thoughts and feelings of the other person, and instinctively adapt to each other.

In some way, the Moon person may also be the cause of their partner undertaking periodical short journeys or improving the relationship with their close relatives and friends. The opposite will be true if the Moon person’s Moon is afflicted.

On the other hand, in social situations, the Moon person could evoke various emotional sensations in their partner: they can be jealous, or, conversely, feel the impulses to care for the Moon person, experiencing the feelings of a parent who first brought their child to a social event.

The purpose of the Moon in 3rd house synastry aspect may be to arouse in the person whose third house is involved an appreciation of the need to pay more attention to the way in which they communicate their ideas to others, refining their approach so as to capture the audience’s imagination and arouse their sympathetic interest.
