Which signs have a compatibility with each other? Do some signs have more affinity with others and not the rest? As a song once asked, “Why can’t we be friends?” It’s possible for ALL signs to match with each other—but some have more capability of doing it with less challenge.
Some signs DO have more bonding with others because they’re in the same elements: the fire-earth-air-water matches. These by nature of their quality of energy will find a connection:
Fire signs: Aries-Leo-Sagittarius
Earth signs: Taurus-Virgo-Capricorn
Air signs: Gemini-Libra-Aquarius
In a similar way, we can line up the zodiac’s 12 signs into two teams:
Signs can also find their compatible matches and challenges by grouping them by modalities of Cardinal, Fixed, or Mutable. Within each group, there will be an opposite-attraction. The remaining two signs left over are NOT in accord by their nature. Another way of looking at this is to put the respective signs on a North-South-East-West 4-way stop sign. The opposite signs will attract; the discordant signs will be at the cross-points:
Aries + Libra
Taurus + Scorpio
Gemini + Sagittarius
Then there are the patterns or interactions of signs which are just stressful by nature: they clash with two elements which are not in harmony. For this reason, I call this union--or the effort to make it work "an itch that can't be scratched; a difficulty of resolution." One way to do this involves the help of the opposition pattern: find the “opposite” sign AND THEN NOTICE WHICH SIGN “ESCORTS” IT ON EITHER SIDE. This forms the quincunx or inconjunct pattern, or 150 degrees. If you're matched with a partner whose sign is inconjunct yours...good luck! You can make it if you try! (sometimes). In a similar way, if you have planets in signs that make this connection, expect a LOT of annoyance within your own psyche as they both try to get their way!
