A
Zodiac signs

Aquarius →

The zodiac sign spanning 300° up to 330° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Aquarius means water-carrier or water-bearer, naming the depicted figure.

How we know · epistemology
Zodiac convention with traditional symbolism

Aquarius occupies the eleventh equal sector and is traditionally fixed air, despite its water-bearer imagery. That classification is symbolic; it does not establish a person's originality or locate the separate and disputed boundaries of an astrological age.

Zodiac signs

Aries →

The zodiac sign spanning 0° up to 30° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Aries means ram; the zodiac sign retains that animal-name.

How we know · epistemology
Zodiac convention with traditional symbolism

The selected zodiac begins with Aries; in the tropical system its origin is the March equinox. Its cardinal-fire classification belongs to traditional interpretation, rather than demonstrating initiative or a fiery temperament in everyone assigned this sign.

C
Zodiac signs

Cancer →

The zodiac sign spanning 90° up to 120° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Cancer means crab; this zodiacal use is the animal-name.

How we know · epistemology
Zodiac convention with traditional symbolism

Tropical Cancer begins at the June solstice, a geometric marker shared across hemispheres despite opposite seasons. Its cardinal-water classification and associated personal themes are traditional meanings, not direct deductions from that seasonal event.

Zodiac signs

Capricorn →

The zodiac sign spanning 270° up to 300° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin-derived constellation and sign name.

Capricorn comes from Capricornus, goat-horned; the traditional figure is a sea-goat.

How we know · epistemology
Zodiac convention with traditional symbolism

Tropical Capricorn begins at the December solstice and is traditionally cardinal earth. The boundary is calculable, while associations with ambition or discipline are interpretive and do not follow from the Sun's seasonal turning point.

G
Zodiac signs

Gemini →

The zodiac sign spanning 60° up to 90° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Gemini means twins, the paired figures behind the sign's name.

How we know · epistemology
Zodiac convention with traditional symbolism

Gemini is the third equal sector, traditionally mutable air. Those classifications organize the symbolic system; they do not establish dual personality, communication skill or another individual trait merely from a planet's presence in the sector.

L
Zodiac signs

Leo →

The zodiac sign spanning 120° up to 150° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Leo means lion; the sign retains the constellation's animal-name.

How we know · epistemology
Zodiac convention with traditional symbolism

Leo is the fifth equal sector and is traditionally fixed fire. The sign uses a defined longitude interval rather than a boundary traced around the Lion constellation; interpretations of confidence or visibility require a separate evidential step.

Zodiac signs

Libra →

The zodiac sign spanning 180° up to 210° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Libra names a balance or weighing scales, the figure retained by the sign.

How we know · epistemology
Zodiac convention with traditional symbolism

Tropical Libra begins at the September equinox and is traditionally cardinal air. The equinox fixes an astronomical reference; the scales imagery and readings about balance or partnership do not themselves provide evidence about a person's relationships.

P
Zodiac signs

Pisces →

The zodiac sign spanning 330° up to 360° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Pisces means fishes; it is a plural Latin animal-name.

How we know · epistemology
Zodiac convention with traditional symbolism

Pisces is the final equal sector, traditionally mutable water, ending where longitude wraps back to zero. The symbolic fish and assigned qualities do not provide a psychological assessment of sensitivity, imagination or susceptibility.

S
Zodiac signs

Sagittarius →

The zodiac sign spanning 240° up to 270° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Sagittarius means archer, from the Latin word family for arrows.

How we know · epistemology
Zodiac convention with traditional symbolism

Sagittarius is the ninth equal sector and is traditionally mutable fire. Its symbol and classification supply a cultural vocabulary; they do not demonstrate that people with this placement share a need to travel or a particular philosophy.

Zodiac signs

Scorpio →

The zodiac sign spanning 210° up to 240° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Scorpio means scorpion. Scorpius is the IAU constellation form.

How we know · epistemology
Zodiac convention with traditional symbolism

Scorpio occupies the eighth equal sector and is traditionally fixed water. These inherited categories structure a reading, but neither its animal imagery nor a calculated placement establishes secrecy, intensity or a hidden motive in an individual.

T
Zodiac signs

Taurus →

The zodiac sign spanning 30° up to 60° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Taurus means bull; the zodiac sign retains that animal-name.

How we know · epistemology
Zodiac convention with traditional symbolism

Taurus occupies the second equal sector and is traditionally classed as fixed earth. The assignment can be checked from longitude, while descriptions of stability or material preference are interpretive themes rather than measured properties of a Taurus placement.

V
Zodiac signs

Virgo →

The zodiac sign spanning 150° up to 180° from the selected zodiac’s origin; constellation boundaries differ.

Word origin, evidence & sources
Word origin · etymology
Latin constellation and sign name.

Virgo means maiden or virgin, naming the depicted human figure.

How we know · epistemology
Zodiac convention with traditional symbolism

Virgo occupies the sixth equal sector and is traditionally mutable earth. A sign assignment describes position within the selected zodiac, not a tested measure of orderliness, analytical ability or a person's relationship to work.
