Term: Triplicity

DEFINITION:

In astrology, the zodiacal signs each have characteristics of one of the four natural elements of fire, earth, water, and air. 
Although it can be confusing to call them triplicities (there are four elements, so shouldn't they be called quadruplicates?), since there are 12 zodiacal signs, the pattern repeats three times to give each sign one of the elements.
