TRINE
A "trine" can simply be a group of three things or, as an adjective, something which is threefold. But the word's main usage is in astrology. The twelve signs in the zodiac are arranged in a circle, in three groups of four, each group containing one sign each of the four elements (fire, earth, air, and water). If two planets are located within two signs sharing the same element, then the angle or "aspect" connecting them is roughly a third of the circle, and this is known as a "trine aspect". Because signs with the same element are supposed to have much in common, the "forces" within them are thought to work together particularly well when connected in a trine aspect. The more so, the closer the angle between the planets comes to exactly 120° (the measure of this deviation is known as its "orb").
