Retrograde
When a planet appears to move backwards through the zodiac from Earth's perspective. It is an optical illusion (the planet is not actually reversing), but the periods are real and they correspond to slowing down or revisiting the matters that planet governs. Mercury retrograde is the famous one.
Retrograde describes the apparent motion of a planet running backwards through the zodiac as seen from Earth. It is an optical illusion — no planet actually reverses direction — but the appearance is real and the periods last weeks or months depending on the planet.
Astrologically these periods correspond to slowing, revisiting, and re-doing the matters the planet governs. Mercury retrograde is the famous one: travel hiccups, communication tangles, jokes about lost keys. Venus retrograde reviews relationships. Mars retrograde dampens action. The slower the planet, the bigger the implication of its retrograde — Saturn and Jupiter retrogrades last months and are part of the year's structure.
AIstra mentions retrogrades because they shape the texture of an entire period rather than a single day. When a forecast opens with "Mercury is retrograde this week," everything that follows is implicitly framed by that backwards drift.
