A.

Accidental rulership Caused by the constant rotation of the Signs in relation to the Houses. Thus it is possible to have any of the 12 Signs on the cusp of the 1st, or indeed any, House. The Sign on the House cusp is said to be the accidental ruler. Also known as Temporary rulership.


Affliction  When a planet or Angle is subject to a difficult aspect it is said to be afflicted.


Air Signs  Gemini, Libra, Aquarius.


Angles  There are four; the ascendant, descendant, Mc and Ic.


Applying aspect  This occurs when two planets approach exactness - zero degrees. Example: Moon at 6 degrees Sun at 10 degrees. The Moon has a faster rotational speed and will therefore catch up to the Sun with the passage of time. In this scenario, the Moon is said to be applying to the Sun. Applying aspects are usually marked in the aspect grid with a + sign. They are of no importance in natal charts, but do find a use in future trends.


Aquarius  The water carrier. 11th Sign of the Zodiac. Positive, Fixed, Air. Ruler - Uranus & Saturn.


Aries  The ram. 1st Sign of the Zodiac. Positive, Cardinal, Fire. Ruler - Mars.


Ascendant  Usually abbreviated to Asc. It is the eastern point of the line of the horizon and the cusp of the first House. Considered to be the most important of the Angles.


Ascendant ruler  The planet ruling the Sign on the cusp of the 1st House. 


Aspects  When two planets form specific angles to each other they are in aspect. [See also Orbs and
individual aspects].


Aspect grid  Used to display aspects in a chart.

B.
Benasp  Short for Beneficent Aspect. Refers to aspects which are considered beneficial.


Benefic  The planets Venus and Jupiter.


Birth chart  The common name for an Astrological chart.

C.
Cardinal Signs  Aries, Cancer, Libra, Capricorn.


Cancer  The crab. 4th Sign of the Zodiac. Negative, Cardinal, Water. Ruler - Moon.


Capricorn  The goat. 10th Sign of the Zodiac. Negative, Cardinal, Water.


Combust  Any planet conjunct the Sun. Some consider this planet to be overpowered by the Sun.


Conjunction  A major aspect of zero degrees. Orb is 8 degrees.


Constellation  A group of stars. There are many, the most notable ones are said to outline a mythological figure, such as Taurus the Bull. These are NOT the same as the Signs of the Zodiac.


Culminate  When a planet arrives at the Mc it is said to be culminating.


Cusp  A line marking the beginning of a House.

<Top>

D.
Debility  A planet in a weak position.


Decanate  An ancient division of the Zodiac not used by modern Astrologers. Each Sign is divided into three divisions of 10 degrees each one ruled by one of the Signs in the triplicity in their natural Zodiac order. For example: in the Sign of Aries, the 1st decanate is ruled by Aries, the second by Leo and the third by Sagittarius.


Declination  The distance a planet is north or south of the equator. Parallels of declination are derived from this.


Decile  An aspect of 36 degrees. Not normally used.


Degree  The Zodiac is divided into 360 degrees, each Sign is 30 degrees.


Descendant  Usually abbreviated to Des. Lies immediately opposite the ascendant and is the western point of the line of the horizon. Also the cusp of the 7th House.


Descendant ruler  The planet ruling the Sign on the cusp of the 7th House.


Detriment  A planet is said to be weakened when in a Sign of detriment. An ancient technique not used much these days.


Dignity  A planet is said to be in dignity and there fore stronger when it lies in a Sign it rules or is exalted in. An ancient technique not used much these days.


Direct  This refers to a planet which has been in retrograde motion and is now moving forward.


Dispositor  Any planet in a Sign is ruled by the ruler of that Sign. This ruler is known as the dispositor. For example; if the Sun, Mercury and Saturn where in Taurus then the ruler of Taurus - Venus - is the dispositor of all three planets. Chains of dispositors, some leading to a final dispositor [See final dispositor] may be formed.


Doctrine of correspondences  An ancient method of categorising planetary rulership of specific objects, traits, events, etc. Also known as the Doctrine of Signatures.

 

Doctrine of   Signatures  Another name for the Doctrine of Correspondences.


Double rulership  Refers to the fact that some Signs - Scorpio, Aquarius & Pisces - have two ruling planets.


Dragon's Head  The north node of the Moon. Said to be beneficial but best ignored.


Dragon's Tail  The south node of the Moon. Said to be harmful but, like the north node, best ignored.

<Top>

E.
Earth Signs   These are Taurus, Virgo and Capricorn.


Eclipse  This occurs when two planets are in the same degree on the ecliptic and are also in the same degree of declination. Only solar or lunar eclipses are used by astrologers.


Ecliptic  The apparent path of the Sun through the heavens. Given this name because eclipses occur on or near to it. It differs from the equator in that it is inclined at 23 ½  degrees to the equator. This inclination gives rise to the seasons.


Electional chart  This is a specialised branch of Astrology dealing with the choice of time for an important event to begin based on the best planetary  positions and aspects for that event. Examples of this are the founding of a business, or best day for a marriage. When this time and date has been selected, the resulting chart is known as an electional chart.


Elements  These are Fire, Earth, Air & Water.


Emphasis  Used to describe any chart factor which stands out in some way. For example: several planets in a House.


Ephemeris  A book containing the planetary positions for each day over a period of time - usually at least one year. It is usual to find these calculated for either noon or midnight. Other information, such as declinations, mutual aspects, times of eclipses, etc. may be included.


Equal House  The primary House system used in astrology. Each House is exactly 30 degrees. The oldest and most reliable House system. There are others known as Quadrant systems, which although popular among some Astrologers are unreliable and best avoided.


Equinox  There are two, spring and autumn. Occurs when the Sun enters the Signs of Aries and Libra respectively. The days and nights are equal when this happens.


Exaltation  A planet in a Sign in which it is said to be exalted is considered to be stronger than normal. An ancient technique not used much these days.

<Top>

F.
Fall  Refers to a planet in a Sign in which it is said to be in detriment and is thus considered to be weakened. An ancient technique not used much these days.


Fire Signs  These are Aries, Leo and Sagittarius.

 

Final dispositor  The planet which disposits all the others is known as the final dispositor and it is considered to be a powerful influence. Opinions differ, but there is some merit in this.


Fixed Signs  These are Taurus, Leo, Scorpio and Aquarius.


Fixed stars  Used by some Astrologers. Like the planets, they are said to have meanings.

<Top>

G.
Gemini  The twins. 3rd Sign of the Zodiac. Positive, Mutable, Air. Ruled by Mercury.


Geocentric  Astrologers assume that the earth is central for the purposes of their work. In actual fact, the Sun is central, but this does not mean that we Astrologers believe the earth is the centre of the Universe in reality.

<Top>

H.
Hard aspects  Another name for difficult aspects.

 

Harmonics  A system first proposed by John Addey which opens up a completely new way of looking at charts by dividing the circle into equal segments, layering them, and then treating the layered segments as a whole circle. For a fuller discussion see Techniques  [Quick Select - Harmonics]. 


Heliocentric  Alludes to the fact that the Sun is the centre of the solar system. A branch of Astrology uses heliocentric charts rather than, or in addition to, normal geocentric  charts.


Horary Astrology  A branch of Astrology which attempts to answer questions based on the chart drawn up at the time of asking the question. Applauded by some, derided by others. I have yet to see convincing proof. 

 

Horoscope  The old term for a birth chart now largely abandoned due to its association with  Sun Sign readings and other types of fortune telling. The modern terms are now natal or radix chart. The original name is derived from the Greek name for the Sun - Horos.


Houses.  A division of the earth into 12 parts. Each division represents a sphere of mundane influences quite specific to the House in question, such as finances, home, career, etc. The equal House system uses Houses of exactly 30 degrees, but other systems do exist.

<Top>

I.

Ic  The planet ruling the Sign in which the Ic is placed.


Immum Coeli  Ic for short. One of the four chart Angles, it equates to the north point in a chart and is directly opposite the Mc. Relates to matters of the home and has similarities with the 4th House.

 

Inceptional charts  Similar to birth charts except used in non-human affairs, such as the founding of a business. Not to be confused with electional charts in which a special time is chosen for the commencement of an event. These charts are drawn up for the time and date when something actually began - after the event.

 

Inferior planets  Not to be taken in its literal sense. Refers to planets lying between the orbits of the Sun and the earth. These are Moon, Mercury and Venus. 


Ingress  The entrance of a planet into a new Sign or House. Major changes can often occur when this happens.


Intercepted  One of those nonsensical terms used in quadrant systems to cover up the inadequacies of the system. When a Sign does not lie on a House cusp it is said to be intercepted. As a result, the planetary ruler of this Sign cannot rule a House!

<Top>

K.
Keyword  A word or phrase used in interpretation which embodies specific information about a planet, Sign or House.

<Top>

L.
Latitude  The distance north or south of the equator in degrees.


Leo  The lion. 5th Sign of the zodiac. Positive, Fixed, Fire. Ruled by the Sun.


Libra  7th Sign of the Zodiac. Cardinal, Positive, Air. Ruled by Venus.


Longitude  The distance east or west of the Greenwich meridian measured in degrees. 

 
Long ascension  So called because they take a long time to rise over the horizon. Cancer to Sagittarius inclusive.


Luminaries  Sometimes known as the 'lights'. They are the Sun and Moon.


Lunar return  Used in future trends. When the Moon returns to its birth position a chart is erected which indicates future trends until the next return. Probably overrated, but is useful in a general sense. As the Moon moves so quickly, the time of birth needs to be quite accurate to give accurate lunar returns. See Techniques [Quick Select - Return Charts]. 


Lunation  The time period between one new Moon and the next. Around 29 days.

<Top>

M.
Mc ruler  The planet ruling the Sign in which the Mc is placed.


Medium Coeli  Mc for short. Also known as the Midheaven. This is the highest point of the ecliptic at any given time. It is the south point of the chart and so has similarities with the 10th House. 


Malefic  Many opinions on this. Generally, Mars and Saturn are considered malefic (bad) but in truth any
planet can be malefic due to bad aspectation. The modern planets, Pluto and Uranus are also classified as malefic. Probably best ignored.


Major aspect  Not to be taken as implying that these aspects are stronger than the minor ones. Conjunction, sextile, trine, opposition & square.


Malasp  Refers to planets having difficult aspects.


Meridian  An imaginary circle passing round the earth from pole to pole through the zenith of the observer. The Sun crosses this at midday.


Midheaven  Another name for the Mc.

 

Midpoints  The point in space lying exactly between two planet (using the shortest distance) is considered to be a sensitive point which embodies the qualities of both planets. The planets need not be in aspect. For a fuller discussion see Techniques  [Quick Select - Midpoints]. 


Minor aspect  Semisextile, Semisquare, Sesquiquadrate, Quincunx. Not to be interpreted as being lesser in effect to the major aspects.


Modes  A name used to describe the Qualities, Elements & Polarity of Signs.


Mundane Astrology  Generally deals with national and worldly affairs using various 'base' charts to predict events.


Mutable Signs  These are Gemini, Virgo, Sagittarius and Pisces.


Mutual aspects  Used to describe aspects between planets in a progressed chart.


Mutual reception  Caused when two planets are in each other's Signs. For example; Mars in Cancer - Moon in Aries. The planets do not have to be in aspect but are obviously stronger if they do. Not used much.

<Top>

N.
Natal chart  Another name for a birth chart.


Natural rulership  This alludes to the natural affinity between Signs and Houses. Aries naturally rules the 1st House, for example. Also applies to planets and Houses. For example; Aries rules the 1st House because it naturally rules Aries which, in turn, rules the 1st.


Negative Signs  These are the Water and Earth Signs.


New Moon  Used by some Astrologers to predict future trends. When the declination is small the new Moon becomes an eclipse which is considered to be a powerful influence.


Nodes  Every planet has its nodes which are the intersection of a planet's path with the ecliptic, but only those of the Moon are used. Of dubious value.


Nonagesimal  The point at 90 degrees from the ascendant. Not used much.

<Top>

O.
Opposition  A major aspect in which two planets are 180 degrees apart. Indicates difficulties and stress. The orb is 8 degrees. Some Astrologers consider this the be the aspect of perfect hatred!


Orbs  Applies to aspects. The orb of a planet (or Angle) is the number of degrees either side of the planet's position in which an aspect can be formed. Varies according to the type of aspect. See Standards [Quick Select - Aspects]. 

<Top>

P.

Parallel  Short for parallels of declination. There are two types - parallel  and counter parallel. The first occurs when two planets are within 1 degree of each other either north or south of the equator. This is similar in action to a conjunction. The second occurs when two planets are within 1 degree of each other on opposite sides of the equator. This is similar to an opposition.


Part of fortune  One of the numerous Arabic Parts. It is a mathematical point in space derived from the relationship between the Sun, Moon and ascendant. Said to indicate fortune. May have some merit, but little used.


Pisces  The fishes. 12th Sign of the Zodiac. Negative, Mutable, Water. Ruled by Neptune and Jupiter.


Polarity  Used to describe the condition of a Sign, either Positive or Negative.


Positive Signs  These are the Fire and Air Signs.


Progressions  Used in predicting future trends. The chart is moved forward in time and then compared with the original, deductions being made from any aspects formed between the two charts or any changes in Sign or House by planets. There are many systems of progression, the main one being Secondary progressions. See Techniques. [Quick Select - Progressions]. 

<Top>

Q.
Quadrants  The division of the heavens into four equal parts. Some Astrologers use these in a similar way to the hemispheres in order to deduce character traits.


Quadrant systems  Are quite different to the equal House system, using complex mathematical rules to derive Houses. Also, the Mc and Ic are taken as the cusps of the 10th and 4th Houses respectively. There are many systems, among the most popular are: Regiomontanus, Placidus, Koch, Porphyry, Campanus, Alcabitus, & Topocentric. Controversy rages as to which is the best, the eventual reason for a preference seems to be 'because it seems to work'. Apart from problems with Signs having no House rulership and planets being in the wrong Houses, it is impossible to produce charts at certain latitudes. Best ignored. See Standards. [Quick Select - Houses]. 


Quadruplicities  See Qualities.


Qualities  Also known as quadruplicities, these are the three conditions of Cardinal, Fixed & Mutable.


Quartile  Another name for a square aspect.


Quincunx  A minor aspect of 150 degrees. Implies difficulties and strain. An orb of 2 degrees is used.


Quintile  An aspect of 72 degrees. No longer used.

<Top>

R.
Radix  Another name for birth chart.


Rectification  The process of attempting to correct inaccurate birth times by various means. Not as scientific and certain as some would have you believe.


Retrograde  Under certain conditions, a planet can appear to be moving backwards in the heavens and is said to be in retrograde motion. Retrograde planets are said to cause delays, frustrations and introspective thinking and going back over old ground. There is some merit in this with transits and progressions, but they are of no consequence in natal charts.


Return charts  When a planet returns to its natal position, a chart can be erected which can be used to determine future trends. Only the solar or lunar returns are of any real value. The other planets cause problems due to retrograde action, not to mention the limits on accuracy imposed by calculation. See Techniques. [Quick Select - Return charts]. 


Rising Sign  Usually known as the ascending Sign, it is the Sign on the ascendant at birth.


Rulership  A complex series of interrelationships between planets, Signs and Houses. It is a powerful tool in Astrological work.

<Top>

S.
Sagittarius  The archer. 9th Sign of the Zodiac. Positive, Mutable, Fire. Ruled by Jupiter.


Satellitium  Another name for stellium.


Scorpio  The scorpion. 8th Sign of the Zodiac. Negative, Fixed, Water. Ruled by Pluto & Mars.


Secondary progressions  The main system used to progress a chart for the purposes of deducing future trends. See Techniques. [Quick Select - Progressions]. 


Semiquartile  Another name for semisquare.


Semisquare  As its name implies, it is half of a square - 45 degrees. A minor aspect, said to be difficult and stressful. Orb is 2 degrees.


Semiquintile  An aspect of 36 degrees. Not normally used.


Semisextile  A minor aspect of 30 degrees. There are mixed opinions on this aspect. My own work suggests that this is a difficult and stressful aspect. The orb is 2 degrees.


Separating. The exact opposite of applying [which see]. Said to be weaker in effect than normal or applying. Of no use in natal charts, but in the case of progressions and transits, there is no doubt that once a planet has reached exactness, its power and effects are greatly diminished.


Sesquiquadrate  A minor aspect of 135 degrees. Indicates difficulties and strain. Orb is 2 degrees.


Sextile  A major aspect of 60 degrees. An active and beneficial aspect. Orb is 6 degrees.


Sidereal time  Differs from clock time in that it is based on the earth's rotation compared to a fixed point in space - zero degrees Aries. Used in Astrological calculations.


Significator  Various meanings for this. Taken to mean a specific type of keyword which can be described.


Shaping  Refers to the distribution of planets around the Zodiac forming certain patterns which have meaning.


Short ascension  Signs which rise fairly quickly over the horizon. Capricorn to Gemini inclusive.


Soft aspects  Another name for the major aspects.


Solar return  A very important method of charting used in future trends. Generally not used by most Astrologers in this country but is gaining favour. Depends on ascertaining the exact time when the Sun return to its birth position. The resulting chart is then used to determine the future trends for the coming year. Very accurate. See Techniques. [Quick Select - Return Charts]. 


Solstice  There are two, summer and winter. Occur when the Sun enters the Signs of Cancer and Capricorn respectively.


Spring equinox  Occurs when the Sun enters the Sign of Aries around the 20th March each year.


Square  A major aspect of 90 degrees. Difficult and stressful, but could be a spur to achievement. Orb is
8 degrees.


Stationary  The point at which a planet appears to stand still before going retrograde or moving from retrograde to direct motion. Of no use in natal charts but can be useful in future trends.


Stellium  Sometimes known as a satellitium. It refers to a group of three or more planets in a Sign or
House. Indicates emphasis.

 

Synastry  A branch of Astrology dealing with relationships by comparing the charts of two people. See Techniques. [Quick Select - Synastry]. 

<Top>

T.
Taurus  The bull. 2nd Sign of the Zodiac. Negative, Fixed, Earth. Ruled by Venus.


Temporary rulership  Another name for accidental rulership.


Transits  A term used to describe the movements of the planets in the heavens over the points of a natal chart. Used to predict future trends. Although some sources advocate using all the planets, this is going too far. In actual fact, Pluto, Neptune and Uranus transits are very useful. Saturn and Jupiter are of limited use, while the rest can safely be ignored. An orb of 1 degree is used between transits and natal planets. See Techniques. [Quick Select - Transits]. 


Trine  A major aspect of 120 degrees. Beneficial and fortunate, although it does not incline towards the grasping of opportunities like the sextile. An orb of 8 degrees is used.


Triplicities  Another name for the elements.

<Top>

V.
Vernal equinox  Another name for the spring equinox.


Virgo  The virgin. 6th Sign of the Zodiac. Negative, Mutable, Earth. Ruled by Mercury.


Void of course  Not used much, except in Horary Astrology. A planet - usually the Moon - is void of course when it reaches that point in a Sign where it can make no further aspects before it leaves the Sign.

<Top>

W.
Water Signs  These are Cancer, Scorpio & Pisces.

<Top>

Z.
Zodiac  A division of the ecliptic into 12 equal Signs of 30 degrees.
