Square
Signs in a square share a modality but belong to different elements. There is a lot of energy and attraction between you, and friction too: you solve the same problems in different ways. These couples grow through conflict, as long as they learn to talk it through.
Elements
Fire and earth combine energy and grounding. The fire partner sparks and inspires, the earth partner gives plans a solid base. You can achieve a lot together if neither pulls too hard: fire wants speed, earth wants guarantees.
Pace and temperament
Both signs are cardinal - initiators used to starting things and leading. Together you launch shared projects easily, but you need to divide roles, or each of you will pull in a different direction.
Aries in love
In love, Aries is the pursuer. It enjoys the chase, shows feelings openly and wants an equally honest response. Boredom and coldness put out its fire faster than arguments do. Aries needs a partner who is not afraid of its energy and leaves room for excitement.
Capricorn in love
Capricorn does not play with feelings - it chooses someone seriously and for the long run. Its love shows in reliability, plans for the future and willingness to take responsibility. Talking about feelings is hard for it, but its word can be trusted. A careless partner makes it wary.
Why one sign isn't enough
Sign compatibility compares only the position of the Sun. Even two couples with the same signs have their Moon, Venus and Mars in different places - which is why it comes easily to some and takes work for others. Exact compatibility is calculated from both partners' birth charts.
