The essence
Mercury is the Roman name for Hermes, the messenger who carried word between gods and mortals and looked after travelers, merchants and thieves alike. In astrology he governs exchange of every kind: language, data, errands, trade and perception. He rules Gemini and Virgo, the signs of curiosity and careful detail. When Mercury stations retrograde, that exchange turns back on itself. The messenger walks his route in reverse, and the prefix re- takes over: revisit, reconnect, rethink, reclaim.
Astronomically, nothing actually reverses. Mercury circles the Sun in about 88 days, far faster than Earth, and as it swings between us and the Sun it seems to slow, stop and backtrack against the stars. Hellenistic astrologers took that motion seriously, treating retrograde planets as turned inward, their themes worked out privately rather than in public.
Modern culture made it shorthand for broken phones and crossed wires. Delays do happen and details slip. Still, this isn't malfunction. It's maintenance, a chance to hear what the noise was covering.
