Aspect
When two planets sit at a specific angle to each other in the sky, that is an aspect. The aspect carries the meaning. It is what makes a forecast say "these two planets are talking right now."
An aspect is the angle between two planets in the zodiac, measured in degrees of separation. Astrology recognises only a handful of those angles as meaningful: 0° (conjunction), 60° (sextile), 90° (square), 120° (trine), and 180° (opposition). Each carries a specific character of relationship.
What makes aspects matter is that they are the part of a chart that actually changes. A planet's position in a sign is a slow context; the aspect it forms with another planet is the temporary, moving conversation between them. When AIstra writes "Mercury squares Mars today," she means today, not in general — by tomorrow the angle will be slightly different.
Aspects are also where the symbolic and the literal meet. A trine between Venus and Jupiter does not predict an event; it describes a tone the day is likely to carry, easy and slightly indulgent. The aspect is the verb of the chart. The signs and houses are the setting.
