To check it by degree: Mercury at 10° Scorpio makes the square with Venus anywhere from 2° to 18° of Leo or Aquarius — the 90° angle give or take 8°. The grid goes by sign, but the square also forms across a sign line: Mercury at 1° Scorpio and Venus at 29° Capricorn are 88° apart, a sextile by sign.

Between two people

What does Mercury square Venus mean in synastry?

The Mercury person's comments hurt the Venus person's feelings, or they disagree about taste and money. Talk can become critical of what the other enjoys. The friction is mild and usually about small things — a film, a purchase, a choice of restaurant — but repeated criticism wears down affection. Balancing every critique with genuine appreciation keeps conversations pleasant.
