When Mercury in your chart forms an aspect to another person’s Neptune. When Mercury in your chart forms an aspect to your partner’s Neptune, empathetic, spiritual, deceptive, or confusing communications figure strongly in your relationship. What type of interaction depends on the aspect that joins Mercury and Neptune, as well as the individuals involved.
Square, Opposition, or Quincunx
When your Mercury forms a challenging aspect (square, opposition, or quincunx) to your partner’s Neptune, you might complain that your partner is vague and indefinite in his or her communications with you. Although you could find each other quite intriguing at first, mistrust could develop over time, as Neptune’s response to Mercury’s pressing questions and statements could end up being deceptive or roundabout. Your Neptune partner could find your statements confining–he/she may perceive you to be too logical or rigid in your thinking. Your partner could attempt to inspire you, but may often feel misunderstood. Your partner might also react by trying to be what he/she perceives you want him/her to be. Misunderstandings could plague the relationship if you are not careful–this is a very challenging aspect in synastry.
When the aspect between Mercury and Neptune is a flowing one (sextile or trine), your Neptune partner helps to inspire your imagination and open your mind. Neptune adds some color to your conversations and your life. You could share similar appreciation for the arts, and enjoy talking about spiritual or artistic topics. You very much “get” what each other is saying, and this is a classic aspect for finishing each other’s sentences.
The conjunction of Mercury and Neptune between charts can possess shades of both the challenging and flowing aspects mentioned above. From our Romantic Compatibility report: There is a poetic, fanciful quality to your conversations. Neptune brings out the poet and dreamer in Mercury. Communications on practical matters, however, may suffer and you both need to be wary of exaggerating, hiding, or deceiving each other. When with Neptune, Mercury is often confused, less clear and less precise than usual, simply because when Mercury wants clear answers, Neptune is rarely forthcoming! Mercury may want Neptune to verbalize and quantify things that Neptune feels should remain unspoken or unsaid!
