Mercury in 12th House synastry – the “Mercurian” individuality helps the Twelfth House personality to penetrate more deeply and thoroughly into its own subconsciousness. The partners form a relationship based on mutual stimulation of the creative imagination. Naturally, this is reflected in their interests in scientific and intellectual activity and in the sphere of beauty.
The personality of the Twelfth House contributes to wider disclosure of the intuitive perception of the “Mercury”, which, in turn, helps the former to better understand and practically realize her intuitive abilities and the possibilities of creative imagination. Such stimulation greatly contributes to the formation of a psycho-emotional connection between partners.
With the negative aspects of Mercury between the partners, difficulties arise in mutual understanding and communication, expressed in the manifestation of embarrassment, insincerity, and isolation on both sides. This affects the integrity of the relationship between them at a subconscious level, which leads to a complete loss of coherence in terms of creativity. The partners fall into laziness, depression, daydreams, etc.
In a positive scenario, Mercury in 12th House synastry partners are able to overcome all internal and external problems.

Mercury in 12th House Synastry Explained
Mercury in 12th House synastry partners may be inclined to talk on mystical topics in your presence. The partner’s speeches can make you excited but will hardly make you trust them or understand what, in essence, he wants to tell you.
It can also be difficult for a Mercury in Twelfth House synastry partner to talk to you because it is not clear where the desire to equivocate and mask his main idea can be completely mastered by him. And if the partner, moreover, is selfish, he will get the opportunity to exploit you promising vague rewards in the future for your very specific services and sacrifices now.
You can maintain this kind of relationship for a long time, especially if you believe the promises. Then your disappointment will be very sharp, and you can even imagine at that moment that your God left you – although in reallity He is coming to help you. At a high level of spiritual development, the Mercury in 12th House synastry partners can help you deal with your deep inner problems (which, to some extent, will show the position of the 12th House in your natal chart).
