Mercury has many functions in astrology. One of these functions is to communicate with other people.
Communication is a vital component of any relationship. This makes this planet one of the primary planets in a synastry analysis.
In addition to governing communication, Mercury also shows a person’s interests, ability to learn, and intellectual curiosity.
Mercury in 1st House Synastry
If someone’s Mercury is in your 1st House, you will get along well with them from the start.
It will be easy to find things to talk about with this person, and you are likely to feel listened to, at least at the start of the relationship.
In and of itself, this placement does not indicate the potential for a long term or serious relationship.
Instead, it indicates that it will be easy to talk with them on a superficial level.
It will be important to look at the aspects between their Mercury and the planets in your chart to determine the potential for communication on a deeper level.
On the other hand, even if problems arise, you will always be able to engage in small talk to renew your connection.
Mercury in 2nd House Synastry
When you talk with someone whose Mercury is in your 2nd House, they will help you feel secure and confident in yourself.
Depending on the other planetary placements and aspects involved, it may be hard for you to engage in small talk with this person.
Your conversation will tend to veer into more serious matters.
You are likely to talk about money with this person, even if it is not a normal topic of conversation for you.
This placement is not necessarily romantic, but it is a good one for people who decide to enter into a long-term relationship.
It will help them to have honest and productive conversations about their finances.
Whatever type of relationship you have with this person, they are in a position to give you good advice about money matters.
Mercury in the 3rd House Synastry
It is very easy to communicate with someone whose Mercury is in your 3rd House.
This person can talk about the things that interest you, and you enjoy conversations with them.
Even if this is someone you just met, they will have a familiar feel to them.
It may even feel like you have known this person all of your life.
Your conversations with this person will tend to be about mundane and familiar matters.
It will be easy to communicate with them over social media. You may have an online relationship with them that is as close or closer than your face-to-face relationships.
Mercury in the 4th House Synastry
You will tend to feel very close to someone whose Mercury is in your 4th House.
This is someone that you can discuss your past and share your childhood memories with.
You will have the sense that this person understands you. You will naturally be very transparent with this person.
The danger to this placement is that you may trust this person more than is warranted.

It will be important to look at the rest of both of your charts to see if your sense of connection is backed up by other planetary aspects and placements.
Mercury in the 5th House Synastry
If someone’s Mercury is in your 5th House, you will enjoy conversations with this person.

This person will help you develop your creativity and will be a good person to bounce ideas off of.
You may think that you have a crush on this person, but be careful, this feeling may be deceptive.
If you do have romantic feelings, it will be important to look to the rest of the synastry between the two of you.
In particular, look to see if there are strong Venus contacts between the two of you as well.
If there are not, you could be mistaking simply enjoying their company for something more that may or may not exist.
Mercury in the 6th House Synastry
It may be hard to communicate with someone whose Mercury is in your 6th House, particularly at first.
You may feel like this person does not listen to you. Even when they seem to be listening to you, they do not seem to understand what you are saying.
You may also experience this person as critical of you, even if they do not intend to be.
Because of this, it may be hard for a relationship with this person to get off the ground.
This could be a superficial difficulty that will go away as you get to know each other better, or it could be a major impediment to any relationship that you may have with them.
It will be important to consider the rest of the synastry between your birthcharts to know for sure.
Mercury in the 7th House Synastry
You will feel a strong intellectual connection with someone whose Mercury is in your 7th House.
This connection will be present from the first time that you meet them.
No matter what type of relationship you have with this person, they will also function as a trusted advisor for you.
This person may not always tell you what you want to hear. Even if you do not like what they have to say, however, it will almost always be valuable.
At times, you may be frustrated by this person, especially if you go to them for support with a conflict you are having with someone else.
This is because this person can see the other side of the situation, and may seem to be siding with the other person.
If this happens, it is important to step back and take in what they have to say. They are giving you excellent feedback, which will almost always be useful to you.
Mercury in the 8th House Synastry
While Mercury is usually a helpful planet and helps with communication, this planet has another, less savory role.
There is a possibility that someone whose Mercury is in your 8th House is playing the role of the trickster in your life.
In any case, this person will be able to see through you on a very deep level. They are also very likely to become privy to your secrets.

Mercury in the 10th House Synastry
Someone whose Mercury is in your 10th House will be able to assist and advise you on your career or public reputation.
This placement is not necessarily indicative of a personal or romantic relationship unless that is shown in other places in the synastry between your charts.

Even if you have a different type of relationship with this person, they will usually still function as a mentor for you in some way.
You can learn a great deal from this person, and they will be able to give you valuable advice.
Mercury in the 11th House Synastry
This is a friendly placement for Mercury, and this person will be a valuable ally to you.
If you are hoping for a romantic relationship, this placement, by itself, will not provide it.
You will need to look to the rest of the synastry between you to determine the likelihood of a romance.

This person is your natural ally, and they will do what they can to assist you. Advice from this person is almost always quite helpful.
Mercury in the 12th House Synastry
Mercury in the 12th House is a complicated placement in synastry.
Like Mercury in the 8th House, this could indicate that this person will play the role of a trickster in your life.
You will need to look at their character and the rest of the synastry between you to assess that danger.
The 12th House is known as the House of Self-Undoing, and this person could tempt you to engage in self-destructive behavior.
On the other hand, this person can be extremely valuable to your personal and spiritual growth.
The 8th House holds the secrets that you keep from others. The 12th House holds the secrets that you keep even from yourself.
A person whose Mercury is in your 12th House will be able to see your blind spots. They can help you see yourself in a very deep way.
The self-knowledge this can provide has the potential to be extremely helpful to you on your spiritual journey.
