Full context:   In Western astrology, the polarity divides the zodiac in half and refers to the alignment of a sign's energy as either positive or negative, with various attributes associated to them as a result. Positive polarity signs, also called active, yang, expressive, or masculine signs, are the six odd-numbered signs of the zodiac: Aries, Gemini, Leo, Libra, Sagittarius, and Aquarius. Positive signs make up the fire and air triplicities. Negative polarity signs, also called passive, yin, receptive, or feminine signs, are the six even-numbered signs of the zodiac: Taurus, Cancer, Virgo, Scorpio, Capricorn, and Pisces. Negative signs make up the earth and water triplicities.
