In astrology, the Arabian/Arabic parts or lots are constructed points based on mathematical calculations of three horoscopic entities such as planets or angles. The distance between two of the points is added to the position of the third to derive the location of the lot.
The ascendant is the astrological sign that is ascending on the eastern horizon at the specific time and location of an event.
Asteroids are relatively new to astrology, having only been discovered in the 19th century. However, some of them, are believed by some astrologers to influence human affairs. Still though, they are often ignored within mainstream systems of astrology, especially in more traditional astrology systems like Vedic astrology or Hellenistic astrology. Their use has become significant to a few Western astrologers yet still only a minority of astrologers use the asteroids in chart interpretation.

In astrology, an aspect is an angle the planets make to each other in the horoscope, also to the ascendant, midheaven, descendant, lower midheaven, and other points of astrological interest. Aspects are measured by the angular distance in degrees and minutes of ecliptic longitude between two points, as viewed from Earth. According to astrological tradition, they indicate the timing of transitions and developmental changes in the lives of people and affairs relative to the Earth.
Astrological compatibility (synastry) is the branch of astrology that studies relationships by comparing natal horoscopes. A natal horoscope is a chart or map of the angles of the planets in the Solar System and their positions in the zodiac at the exact time of a person's birth. These angles represent the positive and negative relationships between the planets. These relationships describe the relationship between the two people under consideration. Compatibility between Zodiac signs is always approached within a particular branch of astrological tradition: Western astrology, Vedic astrology or Chinese astrology.
Astrological progressions are one of the main means used in Horoscopic astrology to forecast future trends and developments. As its name implies, astrological progression involves a method of progressing the Horoscope forward from the moment of the birth or beginning of the subject into the future, and is most usually done for the birth or natal chart of a particular individual.
Astrological transits are one of the main means used in horoscopic astrology to forecast future trends and developments. As its name implies, astrological transits involve a method of interpreting the ongoing movement of the planets as they transit the horoscope. This is most often done for the birth or Natal Chart of a particular individual. Particular attention is paid to changes of sign, or house, and to the aspects or angles the transiting planets make with the natal chart.
Sect is an ancient astrological concept in which the seven traditional "planets" are assigned to two different categories: diurnal or nocturnal sect.
The Behenian fixed stars are a selection of fifteen stars considered especially useful for magical applications in the medieval astrology of Europe and the Arab world. Their name derives from Arabic bahman, "root," as each was considered a source of astrological power for one or more planets. Each is also connected with a gemstone and plant that would be used in rituals meant to draw the star's influence. When a planet was within six degrees of an associated star, this influence was thought to be particularly strong.
In astrology, a composite chart is a chart that is composed of the planetary midpoints of two or more horoscopes. Practitioners of astrology commonly construct a composite chart when two people meet and form a relationship. According to astrologers, the composite chart will give clues as to the nature and function of the relationship.
In astrology, a cusp is the imaginary line that separates a pair of consecutive signs in the zodiac or houses in the horoscope.

The decans are 36 groups of stars used in the ancient Egyptian astronomy to conveniently divide the 360 degree ecliptic into 36 parts of 10 degrees each, both for theurgical and helialical horological purposes. The decans each appeared, geocentrically, to rise consecutively on the horizon throughout each daily earth rotation. The rising of each decan marked the beginning of a new decanal "hour" of the night for the ancient Egyptians, and they were used as a sidereal star clock beginning by at least the 9th or 10th Dynasty.

The descendant forms the cusp of the seventh house of the horoscope and it is one of the angles. It refers to partners or relationships. In the natural chart, the descendant is ruled by the seventh sign of the zodiac, Libra, and its ruler planet, Venus. The sign on the descendant is always the sign opposite the rising sign or the ascendant.

Dodecatemoria are subdivisions of the twelve signs of the Zodiac into a further twelve parts each. These can be said to form a "micro-zodiac" of 144 dodecatemoria, each corresponding to 2.5° of the ecliptic. In an alternate usage, the dodecamorion refers to a point on the ecliptic reached by the addition of twelve times a given number of degrees within a sign, either to the original degree, or to the beginning of the sign.
Essential dignity, in astrology, refers to the relative strength or weakness of a planet or point's zodiac position by sign and degree, or its essence—what the 17th-century astrologer William Lilly called "the strength, fortitude or debility of the Planets [or] significators." In other words, essential dignity seeks to view the strengths of a planet or point as though it were isolated from other factors in the sky of the natal chart.

In astrology, exaltation is one of the five essential dignities of a planet. The exaltation is a place of awareness for the planet, whereas the fall is a position of weakness concerning the function of the planet. The sign position directly opposite a planet's sign of exaltation is considered to be its fall.

The First Point of Aries, also known as the Cusp of Aries, is the location of the vernal equinox, used as a reference point in celestial coordinate systems. In diagrams using such coordinate systems, it is often indicated with the symbol ♈︎. Named for the constellation of Aries, it is one of the two points on the celestial sphere at which the celestial equator crosses the ecliptic, the other being the First Point of Libra, located exactly 180° from it. Due to precession of the equinoxes since the positions were originally named in antiquity, the position of the Sun when at the vernal equinox is now in Pisces; when it is at the Autumnal equinox, it is in Virgo.
Most horoscopic traditions of astrology systems divide the horoscope into a number of houses whose positions depend on time and location rather than on date. In Hindu astrological tradition these are known as Bhāvas. The houses of the horoscope represent different fields of experience wherein the energies of the signs and planets operate—described in terms of physical surroundings as well as personal life experiences.
In astrology, the hyleg is the Persian-Arabic term for the planet with the greatest essential dignity in five important natal chart positions :the degree of the Sun the degree of the Moon the Ascendant the Lot of fortune the pre-natal syzygy

A lunar node is either of the two orbital nodes of the Moon, that is, the two points at which the orbit of the Moon intersects the ecliptic. The ascending node is where the Moon moves into the northern ecliptic hemisphere, while the descending node is where the Moon enters the southern ecliptic hemisphere.

Right ascension is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the point in question above the earth. When paired with declination, these astronomical coordinates specify the location of a point on the celestial sphere in the equatorial coordinate system.
