The 21 astrology terms starting with C, explained simply: meaning, use in chart interpretation and related notions.
Houses (III, VI, IX, XII) that “fall away” after the succedent houses.
The cadent houses are traditionally seen as less powerful for concrete action, yet very important for the mind, communication and spirituality. A planet in a cadent house works more on the level of ideas or preparation than on that of immediate achievement. These houses lay the groundwork for the angle that follows.
The fourth sign (Water/Cardinal), symbolizing emotion, protection and family.
Cancer opens the summer solstice. Ruled by the Moon, it is the guardian of intimacy, memories and the imagination. It represents the matrix, the need for emotional security and the bond with one’s origins. It is an energy of nurturing and care. Highly receptive, it can prove fiercely protective (its shell). Its challenge is not to wall itself off in the past or in excessive emotional dependence.
The tenth sign (Earth/Cardinal), symbolizing ambition, structure and time.
Capricorn opens the winter solstice. Ruled by Saturn, it represents the slow ascent toward the summits, rigor, self-sufficiency and responsibility. It is the builder of society, capable of great sacrifices to reach its long-term goals. Its challenge is to thaw its apparent coldness and pessimism in order to reveal the deep integrity and wisdom that dwell within it.
A mode of energy linked to the start of the seasons, symbolizing initiative and action.
The Cardinal mode gathers the signs that open the seasons: Aries (spring), Cancer (summer), Libra (autumn) and Capricorn (winter). In astrology, a strong cardinal emphasis in a chart points to an initiator’s temperament, an ability to launch projects and a drive toward impulse. It is an energy that pushes forward, creative and dynamic, although it may at times lack perseverance once the initial momentum has passed. The cardinal signs are the ‘engines’ of the zodiac.
The word comes from the Arabic “kashmimi.” The state of a planet within 17 arc minutes of the Sun, granting it exceptional power.
A ‘Cazimi’ planet is considered to be ‘in the heart of the Sun,’ which grants it an extremely powerful and beneficial energy. It is a rare and highly favorable position, for the planet is protected by the solar light and can express its potential to the fullest. For example, Mercury Cazimi is an indicator of great mental clarity and success in communication.
An assessment of the intrinsic strengths and weaknesses of a planet within its sign.
The celestial state determines the moral quality and the power of a planet even before analyzing its concrete action (terrestrial state). It is calculated by adding up its dignities and subtracting its debilities. A planet with an excellent celestial state will produce beneficial results, even in a difficult house.
An asteroid linked to nourishment, motherhood and productivity.
Ceres is the largest asteroid in the main belt. In astrology, it complements the Moon by describing how we care for others in daily life, our relationship to food, to agriculture and to the cycle of loss and reunion (the myth of Persephone).
A chart of the heavens showing the planetary positions at a precise moment.
The chart (from the Greek "thema", that which is set down) is the circular diagram divided into 12 signs and 12 houses. It is the astrologer's principal working tool. Whether natal, horary or mundane, it freezes a cosmic configuration in order to draw symbolic meaning from it. The chart is a mirror of the forces at play, a potential waiting to be unfolded.
An asteroid/centaur symbolizing the “wounded healer.”
Located between Saturn and Uranus, Chiron represents a deep psychological wound that seems impossible to heal in oneself, yet becomes a source of wisdom and healing for others. It shows how to transform suffering into a tool of understanding and compassion. It is the bridge between the personal planets and the transpersonal planets.
A 2nd-century Greek scholar, author of the Tetrabiblos, the founding text of Western astrology.
Living in Alexandria, Ptolemy synthesized the astronomical and astrological knowledge of his time. His work, the “Tetrabiblos,” codified the rules of the signs, planets and aspects that are still used today. He laid the foundations of tropical astrology by tying it to the cycle of the seasons, giving a rational structure to the discipline that dominated learned thought for more than a thousand years.
A planet weakened by its closeness to the Sun (between 17’ and 8°30’).
When a planet is “burnt” by the Sun, its own characteristics are obscured or consumed by the solar power. The individual may struggle to express that function objectively. It is a major accidental debility in traditional astrology. Only the point of Cazimi (the heart of the Sun) cancels this negative effect.
The state of a planet located too close to the Sun (generally less than 8°30’).
A ‘combust’ planet is considered weakened because it is symbolically burnt by the Sun’s rays, making its expression invisible or subject to the solar will. In ancient astrology, this is a serious debility. However, if the planet is within 17 arc minutes of the Sun, it is said to be ‘Cazimi’ (in the heart of the Sun) and instead becomes extremely powerful.
A long-haired celestial body perceived as an omen of exceptional events.
Historically, comets were not included in the natal chart but were studied in mundane astrology as signals of major upheavals or the fall of rulers. Today, some astrologers study their passage in transit as triggers of rapid collective transformation. Yet they remain little used in individual astrology, for lack of sufficient data to interpret them reliably. Comets are messengers of the sky, heralds of profound change, but their symbolism has yet to be fully developed in contemporary astrological language.
A single chart created from the midpoints of two charts, representing the relationship itself.
Unlike synastry, which compares two individuals, the composite chart merges two charts into one by calculating the midpoints of each planet. This chart represents neither partner, but rather the entity 'Couple' or 'Relationship'. It describes the purpose of the relationship, its own destiny and the way it functions as an autonomous unit in the face of the world.
The study of the moment of fertilization to complete the natal chart.
Certain traditions (such as the Trutine of Hermes) seek to calculate the chart of conception in order to rectify the time of birth. The moment of biological incarnation is held to prepare the ground for the birth chart (Radix), offering clues about heredity and the gestation period.
An old term denoting an aspect that blurs the clarity of planetary energies.
In traditional astrology, the term “confusion” denotes a state in which planetary energies mingle in a disordered way, making their expression unclear for the native. This concept is particularly associated with Neptune, the planet of illusion and of the dissolution of boundaries. An aspect of confusion appears when a personal planet (Sun, Moon, Mercury) receives multiple and contradictory aspects, or when it is caught between harmonious and dissonant influences. The native may then feel a difficulty in clearly defining their motivations, feelings or choices in the area concerned. In modern astrology, we more readily speak of “nebulosity” or “haze.” Identifying these zones of confusion in a chart makes it possible to work consciously toward clarifying them.
An aspect of fusion formed when two planets occupy the same degree of the zodiac (0°).
The conjunction is the most powerful and concentrated aspect in astrology. It occurs when two planets (or more) are at the same degree of the zodiac, within orb (generally 8° to 10° for the luminaries, 6° to 8° for the others). Unlike the other aspects, the conjunction is by nature neither harmonious nor tense: it is a fusion. The energies of the two planets blend inseparably, for better or worse depending on the nature of the planets involved. A Venus-Jupiter conjunction is generally a gift of charm and amorous optimism. A Mars-Saturn conjunction can channel formidable energy but can also generate frustration. The conjunction considerably amplifies the planets involved and often forms the focal point of a natal chart. When three or more planets are in conjunction, we speak of a stellium.
A point of symmetrical reflection across the axis of the equinoxes (Aries/Libra).
The contra-antiscion is the point opposite the antiscion. While the antiscion is calculated with respect to the axis of the solstices (Cancer/Capricorn), the contra-antiscion uses the 0° Aries – 0° Libra axis. In interpretation, a planet in contra-antiscion with another often indicates a challenge or a hidden opposition. It is a shadow relationship similar in nature to the opposition, but one that works in a more subtle, almost unconscious way, within the psychic or eventful structure of the chart.
A planet located at the highest point of the chart, near the Midheaven.
The culminating planet is one of the most powerful indicators of vocation and public visibility. It “colors” the whole chart with its energy, for it is the most visible body at the moment of birth. It often indicates the nature of social success and the way the individual is perceived by the community.
The point or dividing line marking the start of an astrological house.
The cusp is the precise degree at which a house begins. The planet that rules the sign on which the cusp falls is called the ‘Ruler of the House.’ In astrology, a planet located just before a cusp (at 2 or 3 degrees) is held to belong already to the following house.
The periodic return of a body to a given position, or the relationship between two bodies.
Astrology is a science of cycles. We distinguish the individual cycle (a planet’s revolution back to its natal position, e.g. the Saturn return at age 29) from the synodic cycle (the meeting of two planets, e.g. the Jupiter-Saturn cycle). Each cycle has a phase of seeding (conjunction), of crisis (square), of flowering (opposition) and of reckoning.
