Astrology Glossary

Every astrology term explained in one plain sentence, alongside chart and transit readings.

• Natal ChartThe map of the sky at the moment and place of your birth — the baseline for your personality and life path. Put together the Sun, Moon, planets, houses and aspects, and you have the full map of your character and life path.
• AscendantThe sign rising on the eastern horizon at your birth — how others first perceive you. It also starts the first house, which sets how all twelve houses are divided.
• MidheavenThe topmost point of the chart, pointing to career, public role and reputation. The opposite point, the IC, points to home and your inner foundation.
• Sun SignThe sign where the Sun sits at your birth — your core self and vitality, the sign most people know. People born on the same day share a Sun sign, but Moon and rising make everyone different.
• Moon SignThe sign where the Moon sits — your emotions, sense of safety and inner needs. It changes fast — roughly every two days — so it needs a fairly accurate birth time.
• Rising SignThe sign of your Ascendant — the mask you show the world and your first impression. It changes about every two hours, so it's the first thing affected by an inaccurate birth time.
• TransitWhere the planets are right now, interacting with your natal chart in real time — the source of daily and monthly forecasts. When reading transits, what matters most is whether a planet aspects your natal planets — not just its sign.
• RetrogradeWhen a planet appears to move backward from Earth's view — in astrology, tied to review, delay and revisiting. Mercury retrograde is the famous one, but Venus, Mars, Jupiter and others go retrograde too, on their own cycles.
• ConjunctionTwo planets very close together, their energies fused — one of the strongest aspects. How strong a conjunction is depends on how close the two planets are.
• OppositionTwo planets facing each other across the sky — tension and balance, asking you to honor both poles. Two planets in opposition usually ask you to find a balance between the two ends.
• TrineTwo planets about 120° apart, flowing easily — often a talent or effortless advantage. But it can also feel so easy that you coast — use it deliberately.
• SquareTwo planets about 90° apart, creating friction and pressure — also the engine of growth. Square pressure, when faced head-on, is often where you grow fastest.
• SextileTwo planets about 60° apart — opportunity and cooperation, if you actively reach for it. Unlike a trine, it doesn't run on its own — you have to reach for the opportunity.
• HouseThe chart's twelve life areas, each house ruling a domain of life. Houses tell you which area of life is involved, complementing a sign's 'how'.
• AspectThe angular relationship between two planets, deciding whether their energies cooperate or clash. The major aspects are conjunction, sextile, square, trine and opposition, each with its own strength and theme.
• FirdariaA medieval timing system that divides life into sequential planetary periods, showing which planet rules the present. Firdaria major periods span years and frame whole chapters; minor periods break them into shorter stretches.
• SynastryOverlaying two people's charts to see the attraction and friction in a relationship. Start synastry with the Moon, Venus and anything touching the seventh house — the relationship's tone lives there.
• StelliumThree or more planets crowded in one sign or house, making that area stand out. The sign and house of a stellium become the person's most focused energy outlet.
• Grand TrineThree planets each in trine, forming a closed triangle — a classic pattern of flowing talent. Its ease can bring inertia — watch for energy circling only in comfortable territory.
• T-SquareTwo planets in opposition, both squared by a third — a tense but high-drive configuration. The apex planet of a T-square holds the key — pressure usually finds its outlet there.
• ZodiacThe twelve-sign band the Sun travels through in a year, and astrology's basic coordinate system. In a chart, a planet's sign colors how that planet expresses itself.
• Solar ReturnThe chart drawn for the moment the Sun returns to its birth position each year, used to read the coming year's themes. It answers the overall mood of the year, not what happens on a specific day.
• Secondary ProgressionsA timing technique that advances one day after birth as one year of life, showing the inner evolution of the planets. It reflects slow inner shifts and is usually read alongside transits.
• EphemerisTables recording the exact position of the planets for every day — the raw data behind chart calculation. Modern tools compute this automatically with tables like Swiss Ephemeris, so you never look it up by hand.
• Sidereal ZodiacThe zodiac measured against fixed stars, unlike the tropical zodiac measured from the vernal equinox. Vedic astrology primarily uses the sidereal zodiac, so signs can differ from the tropical system.
• YodA pattern where two planets sextile each other and both are quincunx (150°) to a third. Often read as a finger of fate pointing to a life theme that asks for special attention.
• Grand CrossFour planets in opposite pairs, all squaring each other in a closed square pattern. It creates constant tension, but also a powerful engine for action.
• KiteA grand trine plus one planet opposing one of its points, shaped like a kite. The grand trine gives smooth talent; the opposition point is where that talent gets grounded.
• North NodeOne of the Moon's orbital nodes crossing the ecliptic — in astrology, the direction your soul is growing toward. It opposes the South Node (the familiar path) and is often called the soul's lesson.
• ChironA body in the asteroid belt, read in astrology as the deepest wound and its healing. The wound it points to tends to hurt first, then heal — and often lets you help others with the same pain.
