Term standard

adjacent

Adjacent: a 30° separation. It is not one of the four configurations classified as harmonious or discordant in Tetrabiblos I.16; the kernel reports it as geometry only.

aspect

Aspect: the angular distance between two bodies measured along the ecliptic, read in fixed classes (conjunction, sextile, square, trine, opposition), each with its own allowed orb.

bamen

The eight gates of the human plate: Open, Rest, Life, Harm, Delusion, Scenery, Death and Fear.

baoshouguan

The brow, one of the five officials.

biangua

The hexagram produced when moving lines change.

bijian

Same element and polarity as the day master; read as peers and rivals.

composite

Composite chart: every body folded to the midpoint of the two people's positions along the shorter arc, giving one figure that belongs to the pair rather than to either person. An exact 180° separation has no unique short-arc midpoint and is rejected rather than quietly resolved.

conjunction

Conjunction: two bodies at the same ecliptic longitude (0°, orb 8°). Tetrabiblos lists it apart from the aspects proper, so classical wording must be quoted separately.

dayun

The ten-year luck pillar sequence derived from the month pillar and the year's polarity.

dongyao

A line drawn with old yin or old yang, hence changing.

ershibaxiu

The twenty-eight lunar lodges assigned one per day in continuous order.

fanyin

A course where the monthly general and the hour branch are in opposition, so the heaven plate is reversed.

feishen

The visible line sitting above a hidden one.

fumu

Kin label: what generates the palace element; reads as shelter, documents and elders.

fushen

A kin-line absent from the hexagram, borrowed from the palace head hexagram and placed under the same line position.

fuyin

A course where the monthly general and the hour branch coincide, so the heaven plate rests on the earth plate.

guangui

Kin label: what overcomes the palace element; reads as office, illness and unseen pressure.

heidao

The other six offices, classed as black-road days.

house_system

House system: the rule dividing the wheel into twelve houses. This kernel implements exactly three — Placidus, whole sign, equal — and a fourth is not offered; two systems give different houses for the same sky, so the choice is a declared basis and enters the chart checksum.

huangdao

The six offices traditionally classed as yellow-road days.

hugua

The hexagram built from the middle four lines.

jianchu

The twelve day-offices cycling from the month builder.

jiecai

Same element, opposite polarity; read as company that takes.

jiesha

The first of the Three Killings: the branch at the "severance" stage reached forward from the year's triple-harmony birth position; it heads the killing sector.

jingshenneishou

Keeping the spirit within, from the Suwen; used here as a description of attention, not a medical claim.

liuchong

All three line-pairs in clash; ten hexagrams satisfy it structurally.

liuhe

All three line-pairs in six-harmony; eight hexagrams satisfy it.

liuqin

The five kin labels plus the subject itself, assigned by how each line's branch relates to the palace element.

lunar_return

Lunar return: the same solve for the Moon coming back to its natal longitude, within a 34-day window (the Moon cycles in about 27.3 days).

major_arcana

The 22 trumps of a 78-card tarot deck (Fool through World), numbered 0–21; their numbering order differs between decks (Waite swaps VIII and XI).

minggong

The life palace located from the birth month and hour.

minggua

The person's trigram derived from birth year and sex in the eight-residence system.

minor_arcana

The 56 suit cards of a tarot deck, four suits of fourteen (ace to ten plus four court cards).

najia

The system assigning a stem-branch pair to each line by its trigram.

opposition

Opposition: 180° apart (orb 8°). Classed as discordant in the same chapter, alongside the square.

piancai

What the day master overcomes, same polarity; read as unsteady or shared wealth.

pianyin

What generates the day master, same polarity; read as protection with a cold edge.

qicai

Kin label: what the palace element overcomes; reads as wife, money and things owned.

qisha

One of the ten gods: the element that overcomes the day master with the same polarity; read as pressure, authority and the thing that must be handled.

quincunx

Quincunx: a 150° separation, likewise outside the four configurations classified in Tetrabiblos I.16; the kernel reports it as geometry only.

reversed

Reversed: the card came out upside-down. Modern teaching holds three coexisting conventions (inversion, weakening, inward/delayed), so a reversal is a reading instruction, not an automatic flip of the judgement.

sanchuan

The initial, middle and final transmissions; the sequence read as the course's development.

sanqi

The three wonders: Yi, Bing and Ding.

sansha

The three branches opposed to the year's elemental direction.

santing

The vertical three-part division of the face; two public measurement bases exist and are kept separate.

secondary_progression

Secondary progression: one solar day after birth stands for one year, so the progressed figure is cast at birth instant + age_years days. The arithmetic is on UTC instants, so the wall clock may end up an hour off across a DST change - which the chart records.

sextile

Sextile: 60° apart (orb 6°). Tetrabiblos I.16 classes it with the trine as harmonious, because it falls between signs of like sex and kind.

shangguan

What the day master generates, opposite polarity; read as talent that clashes with authority.

shishen

What the day master generates, same polarity; read as output, appetite and ease.

shiyao

The line holding the self position in the eight-palace scheme; the subject of the reading.

shouyi

Guarding the One, from Baopuzi; kept here as sustained attention without the chapter's supernatural claims.

sike

The four courses: day stem, its lodge, the day branch and the branch's upper god; the base grid from which the three transmissions are chosen.

sitian

The qi presiding over the year's upper half.

solar_return

Solar return: the chart cast for the instant the Sun comes back to the ecliptic longitude it held at birth; this kernel solves it within a 380-day window and records the residual.

spread

Spread: the fixed set of positions a reading draws into (Celtic Cross, Time Line, single); each position carries its own question.

square

Square: 90° apart (orb 6°). Older English translations call it "quartile"; the kernel records it under the modern name — one and the same aspect, not two.

suipo

The branch clashing the year spirit.

suisha

The third of the Three Killings, at the "nurturing" stage; worst in the four opening years, and in Mao and You years it stands in six-cycle union with the Grand Duke.

synastry

Synastry: the aspects formed between two people's bodies - each person keeps their own chart, and the relations are read across the two sets.

taiyuan

The conception pillar taken from the month pillar.

tiande

A monthly virtue-god; which stem or trigram it is depends on the month.

tiyong

The still trigram (ti) and the moving one (yong); the pair whose generation-and-overcoming is read.

transit

Transit: aspects taken between the bodies at the moment asked and the bodies of the radix figure - two rings compared, not one chart read again.

trine

Trine: 120° apart (orb 6°), booked as harmonious in the same classical chapter.

upright

Upright: the card came out facing the reader, and is read with its standard keyword set.

wuguan

The five official features in physiognomy.

xunkong

The two branches left over in the current ten-day decade; lines sitting there are "empty" in the technical sense.

yingyao

The line two places beyond the self line; the counterpart.

yongshen

The single line chosen to represent the matter asked about; chosen by the question, not by the board.

yuanshou

The first of the nine course methods: one upper element controls a lower one and no other course has a control.

yuede

The monthly virtue tied to the month's element.

yuejiang

The monthly general: the sun's position mapped to one of the twelve generals, used to set the heaven plate.

zaiquan

The qi presiding over the year's lower half.

zaisha

The second of the Three Killings, at the "conception" stage; the Xieji, juan 34, takes it as the worst in the four cardinal years and (on the book's own hedge 「略与」, "roughly equal") the four seasonal years.

zhaigua
