Angles: These are the Ascendant (ASC), Decendant (DSC), Midheaven (MC), and Innum Coeli (IC), referring to the cusps of the 1st, 7th, 10th, and 4th houses, respectively.

Aspect: The position of planets or stars with respect to one another.

Conjunct: An aspect formed when two planets are in the same sign, 0 degrees apart. The planets blend their energies.

House: The horoscope divides the heavens into 12 houses. Each house has rulership over specific areas of life. If the signs of the zodiac show “how” planets express themselves, the houses of the natal chart reveal “where” these energies play out. Each of the twelve houses of a chart rule certain areas of life, types of people and relationships, ideas, and life circumstances.

Quincunx: Used interchangeably with "Inconjunct", it occurs when two planets are roughly 150 degrees apart. The planets in a quincunx don't mesh and the signs are of different elements and modalities. For example, Leo (Fixed Fire) and Pisces (Mutable Water). People with a quincunx in their charts tend to compartmentalize the two areas of life represented by the planets, but the challenge is to find a working balance between the two.

Sextile: An aspect formed when planets are two signs - or about 60 degrees - apart. It is a positive harmony between planets that opens up new pathways for growth.

Square: When you divide the natal chart by 4, you get a 90° angle. This is the square planetary aspect, which represents the challenges and conflicts between the planets involved. When the planets are square to each other, each planet becomes stressed and each side must put in effort to come to a compromise.

Station: The point at which a planet changes its apparent direction from direct to retrograde, or vice-versa. A station is the strongest point of energy release in a planet’s cycle.

Transit: The ongoing movement of planets in contrast to their positions at the moment of one's birth or otherwise noteworthy moment in the past. Transiting planets affect our current reality and specifically, you, through the lens of the snapshot that your natal chart represents. For example, when Venus transits through one's 5th House (love, romance, friendship) one can expect to experience a surge in interpersonal relationships.

Trine: The advantageous or favorable astrological aspect of two planets 120 degrees apart. Trine generally relates to "flow", with planets in a harmonious angle of support.

Yod: Also called the "Finger of God", a yod is a triangular aspect with one planet at the top in quincunx to two others in sextile. The planet at the apex represents a special purpose or task beneficial to one's evolution. A yod is considered to be a constant and unchanging condition.
