Zodiacally Speaking The signs of the Zodiac, derived from the teachings of Astrology, are assigned to individuals based on their date of birth. Astrology further groups the signs of the Zodiac into four elemental categories: earth, fire, water, and air. Compatibility between signs is similar to these elements in nature:
Fire signs are most compatible with air signs. Likewise, air signs are most compatible with fire signs.
Water signs are most compatible with earth signs. Likewise, earth signs are most compatible with water signs.
Generally speaking (but there are exceptions) people with the same Zodiac sign aren't as compatible with each other simply because they can become too comfortable, hindering each other from balance and growth.
