A
Aspects & angular relationships

Applying aspect →

An aspect currently moving toward exactness, judged from the bodies’ relative motion; a later station can interrupt it.

Word origin, evidence & sources
Word origin · etymology
Descriptive participial phrase.

Applying uses apply in the older sense of drawing toward or bringing together; the aspect is moving toward exactness.

How we know · epistemology
Local motion test

Relative motion shows whether a contact is approaching exactness at that instant. A later station or change of direction can interrupt it, so application alone does not establish future completion.

Aspects & angular relationships

Aspect →

A specified angular relationship between chart positions, usually measured in zodiac longitude; different schools select different angles.

Word origin, evidence & sources
Word origin · etymology
Latin through Middle English.

Latin aspectus, from aspicere, means a looking at. The name retains the old metaphor of planets seeing one another.

How we know · epistemology
Measured angle plus selected rule

Angular separation is computable, but selecting meaningful angles, tolerances and interpretations is conventional. A detected aspect establishes the stated geometry, not a causal connection between the represented life topics.

C
Aspects & angular relationships

Conjunction →

An aspect near 0° separation in the chosen coordinate measure; matching longitude does not guarantee physical closeness.

Word origin, evidence & sources
Word origin · etymology
Latin-derived noun.

Conjunction belongs to the family of conjunct, joined together. The astronomical use names bodies meeting in a shared direction.

How we know · epistemology
Angular criterion

A conjunction is a match in the chosen angular coordinate within an orb. Different latitudes and distances can separate the bodies physically; interpretive blending is not implied by longitude alone.

Aspects & angular relationships

Contra-parallel →

Also: contraparallel

Two objects with nearly equal declination magnitudes on opposite sides of the celestial equator.

Word origin, evidence & sources
Word origin · etymology
Latin prefix on a geometric term.

Contra- means opposite or against; it marks equal-sized declinations on opposite sides of the celestial equator.

How we know · epistemology
Equatorial angular criterion

The comparison matches declination magnitudes across the celestial equator. Its geometry is testable, but equating it with a zodiacal opposition adds an interpretive correspondence.

O
Aspects & angular relationships

Opposition →

An aspect near 180° separation in zodiac longitude.

Word origin, evidence & sources
Word origin · etymology
Latin through French.

From oppositio, placing against or opposite. The geometry uses the same opposed-position idea for a half-circle separation.

How we know · epistemology
Angular criterion

The geometry is near half a circle in the chosen coordinate. Reading it as tension or complementarity is a traditional analogy, not a measured conflict between people or forces.

Aspects & angular relationships

Orb →

The permitted distance from an exact aspect. Different techniques use different limits.

Word origin, evidence & sources
Word origin · etymology
Latin through French.

Latin orbis means circle, disk, or sphere. Astrology extended the surrounding-circle idea to a permitted range around exact contact.

How we know · epistemology
Practitioner tolerance

An orb decides which near-matches count under a technique. Widening it changes the result set, so the tolerance must be declared before comparison; it is not a measured radius of influence.

P
Aspects & angular relationships

Parallel of declination →

Also: declination parallel

Two objects at nearly the same declination, using a stated tolerance.

Word origin, evidence & sources
Word origin · etymology
Geometric phrase.

Parallel comes from Greek language for being beside one another; of declination specifies the coordinate being matched.

How we know · epistemology
Equatorial angular criterion

The comparison uses matching declinations within a stated tolerance. It is not a zodiac-longitude conjunction; any analogous interpretation is a school’s choice rather than a consequence of coordinate equality.

Q
Aspects & angular relationships

Quincunx →

Also: inconjunct

A modern aspect near 150°; historical uses of “inconjunct” can instead mean signs lacking a recognized classical aspect.

Word origin, evidence & sources
Word origin · etymology
Latin numerical name.

Quincunx literally means five twelfths, from quinque and uncia. Five twelfths of the zodiacal circle is 150 degrees.

How we know · epistemology
School-dependent angular rule

The modern 150° aspect is a chosen relationship. Older descriptions of signs lacking a classical aspect use a different concept, so sharing a name does not establish equivalent calculations or meanings.

S
Aspects & angular relationships

Separating aspect →

An aspect currently moving away from exactness, judged from the bodies’ relative motion.

Word origin, evidence & sources
Word origin · etymology
Descriptive participial phrase.

Separating means moving apart after contact; the label describes an aspect whose exact meeting has already passed.

How we know · epistemology
Local motion test

Relative motion shows the contact moving away from exactness. Interpreting that geometry as a completed life event requires a separate rule; it does not independently identify what happened.

Aspects & angular relationships

Sextile →

An aspect near 60° separation in zodiac longitude.

Word origin, evidence & sources
Word origin · etymology
Latin borrowing.

Latin sextilus means sixth, from sextus. The aspect is one sixth of the circle.

How we know · epistemology
Angular criterion

The relationship is near one sixth of a circle. Treating it as cooperation or opportunity is an interpretive convention; the angular measurement cannot establish that an opportunity exists.

Aspects & angular relationships

Square →

An aspect near 90° separation in zodiac longitude.

Word origin, evidence & sources
Word origin · etymology
Ordinary geometric name.

Square names the four-sided equal-sided figure; the astrological aspect corresponds to one quarter of the circle, or a right angle.

How we know · epistemology
Angular criterion

The relationship is near a quarter circle under a stated orb. Traditional difficulty symbolism should not be confused with an observed physical obstruction or a guaranteed adverse event.

T
Aspects & angular relationships

Trine →

An aspect near 120° separation in zodiac longitude.

Word origin, evidence & sources
Word origin · etymology
Latin through French.

Latin trinus means threefold, from trini, three each; a trine spans one third of a circle.

How we know · epistemology
Angular criterion

The geometric relationship divides the circle into thirds. Its usual favorable symbolism is inherited interpretation; identifying a trine does not demonstrate ease, talent or an eventual success.
