In synastry, Moon square Mercury can be a difficult aspect, but it still indicates a certain amount of compatibility.
The Moon plays multiple roles when it comes to relationships. One of these roles involves communication.
While communication is one of many areas governed by the Moon, it is Mercury’s primary domain. Because of this, it plays a primary role in whether a relationship will survive and blossom.
A square is a tricky aspect in synastry. It is tense, but it is a connection. When it comes to Mercury, any connection, even a difficult one, is better than no connection at all.
Moon Square Mercury in Synastry
Moon square Mercury in synastry will produce some difficulties when it comes to communication. On the other hand, it will also pressure the people involved to keep trying to communicate, even if it is a struggle.
Because of this pressure, the overall impact of this aspect tends to be more positive than negative in the long run.
There will often be a lot of conflicts when this aspect is present, especially if it is particularly close. Still, unless there are a lot of other volatile aspects between the two, they should be able to work things out over time.
They will not be able to let things go or “agree to disagree,” even if they want to. Arguments will weigh on their minds until they are resolved.
There are certain sign combinations that can make this aspect either more positive or more negative than it would ordinarily be.
Gemini and Virgo
Mercury rules both of these signs. Because of this, the two will talk a lot. They may disagree from time to time, but they will both enjoy their debates.
The impact will be largely the same whether Mercury is in Gemini or Virgo. Both combinations of this aspect will make it much more positive.
Gemini and Pisces
Mercury is strong in Gemini but has a lot of difficult with Pisces.
This aspect will be slightly more positive than it would ordinarily be if the Moon is Gemini and Mercury is in Pisces. In this case, the two will be able to help each other and develop a healthy interdependence.
If the Moon is in Pisces and Mercury is in Gemini, however, this aspect will be far more negative. The two will struggle to find common ground, and they may give up trying out of frustration.
Virgo and Sagittarius
This is another case in which Mercury is strong in one sign and weak in another. Virgo is one of Mercury’s home signs, and Sagittarius is enemy territory.
This aspect will be more positive if the Moon is in Virgo and Mercury is in Sagittarius. In this case, the two will be able to balance and complement each other.
If the Moon is in Sagittarius and Mercury is in Virgo, however, this aspect can become quite negative. It will be important to look to the other aspects between them to see if they will be able to come together.
Sagittarius and Pisces
Mercury struggles in both Sagittarius and Pisces. This means that the positive effects that this aspect usually has on communication will not be present.
Furthermore, these two signs tend to lack staying power, so these two are likely to give up rather than work through their difficulties. It will be important to look to see whether the chart of either person has other planets that will suggest perseverance before making a final analysis regarding this combination.
The negative impact will be the same regardless of whether Mercury is in Sagittarius or Pisces.
House Position
The houses in each person’s chart that are impacted by this aspect will play a key role in how it will manifest.
