Mercury in the first house
Mercury rejoices in the first house, and the mind sits close to the surface of the person. Thinking, speaking and gesture are part of the physical presence; people notice the talk, the quickness, the alert look. Identity is bound up with being understood, and self-definition happens through explanation. There is often a youthful appearance and a nervous energy that needs discharging. Learning is constant and largely self-directed. What this placement asks is that the words match the life, so the fluency describes a person rather than standing in for one.
Mercury rejoices in the first house. It is the one house the tradition says this planet is at ease in whatever sign it holds.

Which sign holds it
Under whole-sign houses the rising sign settles every other house at once. If you know your Ascendant, this is the sign your first house holds and the planet that rules it.

Quadrant systems such as Placidus cut the houses by the angles instead, so a planet near a cusp can land in a different house from the whole-sign answer. The chart page shows both.
Reading it in context
A keynote is a starting point, not a verdict. What Mercury actually does in your first house depends on its sign, its aspects, its dignity, and whether it is in sect. Two people with the same placement and different charts around it live it differently.
