Terms
Synonym: bounds
The Latin word "termini" means limits, confines - i.e. not a single degree but an area.[1]
In Hellenistic times the terms were called hories.
Traditionally, each sign is divided into five sections of unequal length. One of the five traditional planets (excluding the sun and moon) rules each of these sections. A planet within the segment that it rules is in its own terms.
Ptolemy in the second century CE in his Tetrabiblos[2] described two different types of terms: Egyptian and Babylonian. However, the rationale behind these divisions of the zodiac is lost.
The terms are one of a planet's essential dignities. They depend on its placement in the Zodiac, irrespective the Houses. Nowadays the terms still are used in Horary Astrology and in Electional Astrology. Not very often, though, because their system is not so simple and logical as the Decans. And because in the meantime we have several, slightly different systems:
Al-Biruni's Egyptian Terms
The Persian-Arabian astrologer Al-Biruni's terms are based (mainly) on those of Firmicus Maternus and can be found in the Tetrabiblos, 1.20.[3]

Lilly's Ptolemean Terms[4]
Hellenistic astrologers argued quite early about the "correct" terms. Lilly called his sytem - which among astrologers widely was accepted since the Renaissance times - Ptolemaic, though actually its origin was not clear at all.
