Mercury governs thinking and speech — how you process and explain. In Gemini, that function takes on curiosity, quickness and a need for variety — a Mutable Air expression ruled by Mercury.
Where it strains
Starts more than it finishes, and uses cleverness to avoid depth.
Reading a placement properly
Mercury in Gemini describes a function in a style. It says nothing yet about where that plays out — for that you need the house, and the house needs a birth time. A placement read without its house is half a sentence.
