Zodiacs: Overall

for better understanding:

1. Gender of signs:
   Fire and Air signs are masculine (energy flows outward);
   Earth and Water signs are feminine (energy flows inward).
   
   
2. the Elements:
   a) Air - pleasure, because fun in important!
   b) Earth - wealth, because you can have fun for very long without some money.
   c) Fire - morality, because someone else is going to interfere with your money and fun unless we all agree to cooperate and get along with each other.
   d) Water - enlightenment, because eventually you want a deeper type of happiness than simple "fun."
   
   
3. Development types:
   a) Expanding - moving one step at a time
   b) Rooting - remaining at one point
   c) Oscilating - jumping from one point to another point far away
   
   
4. Modalities:
   a) Cardinal - unstoppable force
   b) Fixed - immovable
   c) Mutable - fluid and flexible
   

Thus, by adding 2 of the ingredients (elemental n development):

Aries - expanding fire sign;
Leo - rooting fire sign; and
Sagittarius - oscilating fire sign.

Taurus - rooting earth sign (earth and rooting go well together, thus Taurus is a fertile and productive sign);
Virgo - oscilating earth sign (earth and oscilation go poorly together, therefore Virgo is a sign connected with frailty); and
Capricorn - expanding earth sign.

Gemini - osciliating air sign (thus the most "airy" since oscilation and air are so complimentary),
Libra - expanding air sign; and
Aquarius - rooting air sign (another challenging combination).

Cancer - expanding water sign (needing, progress towards emotional enlightenment);
Scorpio - rooting water sign (a challenging proposition: stable water); and
Pisces - oscilating water sign (flows here and there indescively).
