☉ Sun in Gemini
Sun in Gemini means the sun stood in Gemini at the moment you were born. Sun meets gemini: core identity — what you are at the centre. It moves through a sign in about 30.3 days, which is short enough for the placement to be personal.

Sun governs core identity — what you are at the centre. 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
Sun 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.
