Astrology glossary

These definitions are starting points, not shortcuts to a verdict. Use a term to find its place in the chart, then follow the linked guide to see how it works with the other layers.

Astrological language is symbolic. It can support reflection and conversation, but it cannot diagnose people, replace evidence-based care, or make certain promises about a future.

Birth chart foundations

Birth chart

A symbolic map of the sky for a birth time and place. A useful reading connects signs, planets, houses, and aspects rather than isolating one placement.

Planet

In astrology, planets represent different functions such as vitality, emotion, thought, relating, action, growth, and limits. The Sun and Moon are included in this symbolic language.

House

One of twelve life-area divisions in a birth chart. Houses help locate where a theme may become noticeable; they do not guarantee an event.

Aspect

A geometric relationship between two planets. Aspects describe how symbolic functions may combine, support, challenge, or call for adjustment.

Ascendant / rising sign

The zodiac sign rising on the eastern horizon at birth. It begins the first house and is highly sensitive to birth time and birthplace.

Chart ruler

The planet traditionally associated with the Ascendant sign. Its placement and connections add context; it is not a single “main personality planet”.

Timing and relationships

Transit

A current planetary position compared with a birth chart. Transits are often used to reflect on timing and attention, not to predict fixed outcomes.

Retrograde

An apparent backward motion viewed from Earth. In astrology it is commonly treated as a prompt to review a theme, not as a universal warning or excuse for harm.

Synastry

A comparison of two birth charts used to explore relationship patterns. It should be paired with consent, communication, safety, and real-world context.
