Same sign
Partners of the same sign mirror each other: the same values, reactions and pace. That gives instant understanding, but also amplifies shared weaknesses - nobody balances out the extremes.
Elements
Two earth signs build a relationship on solid ground. You value reliability, clear plans and material security, and you are comfortable sharing a practical rhythm. The risk is routine: without new experiences the relationship can turn into a well-run household with no spark.
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.
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.
