Mercury in the eleventh house: thinking, speaking and learning, worked out through friendship and hopes.
The short answerMercury in the eleventh house puts thinking, speaking and learning into the department of friendship and hopes. Mercury brings thinking, talking and restlessness, and the eleventh house governs friends, groups, hopes and the future. It is a succedent house, so the placement works steadily and shows up as a resource.
Mercury rules thinking, speaking and learning, and keeps asking how do I process the world. The eleventh house is where friendship and hopes happens. Put them together and you get a person for whom friendship and hopes is not a neutral background subject: it is where thinking, speaking and learning gets worked out.
In practice that usually means more of it, and more consciously. People with a planet in a house tend to think about that house's subject more than people without one, whether or not they have an easier time of it.
Where it strainsThinking in this department has a cost, and the honest version is this: it produces a great deal of thinking about the subject and not always much doing. In the eleventh house that shows up around friendship and hopes specifically, rather than everywhere.
Which sign your Mercury would be in
A planet does not land in a house by itself. The sign it is in, combined with your rising sign, is what puts it there. Using whole sign houses, here is the sign your Mercury would have to be in for it to fall in your eleventh house.

Find your rising sign, and the third column tells you which planet-in-sign page also applies to you. The sign describes the style; the house describes the department. Both halves are needed.
The same placement, four very different people
This is where planet-in-house descriptions usually stop being useful, because the house says what department and the sign says how, and the how changes everything. Four versions of Mercury in the eleventh:
In a fire sign, Mercury handles friendship and hopes fast and visibly. It acts first. The department moves, and some of the movement has to be undone later.
In an earth sign, slowly and concretely. Nothing counts until it exists, which makes this version reliable and slow to start.
In an air sign, through talking and thinking. The department gets analysed thoroughly, sometimes instead of being acted on.
In a water sign, by feel. This version reads the situation before anybody has explained it, and struggles to justify a conclusion it already knows is right.
The table above tells you which of those four applies to you, because the sign on your eleventh house follows from your rising sign. A reader who skips that step and takes a generic description of Mercury in the eleventh is reading a blend of twelve different placements.
The natural sign of this house is Aquarius, which is where the house's general reputation comes from. That is useful background and it is not your chart unless you happen to be an Aries rising.
The eleventh and the fifth
Every house has an opposite, and the two are read as one axis. The eleventh of friendship and hopes sits opposite the fifth of romance and creativity. A planet in one of them is always saying something about the other: Mercury in the eleventh tends to produce a particular relationship to romance and creativity as well, usually by neglect or by overcorrection.
What it is not
It is not a prediction. Mercury in the eleventh house does not mean a specific event in friendship and hopes will happen to you. It describes where thinking, speaking and learning is concentrated, and concentrations cut both ways.
It is also not the whole story about friendship and hopes. The sign on the house, the planet that rules that sign, and where that ruler sits elsewhere all matter, and in a chart where they disagree with the planet sitting in the house, they often win. The eleventh house page covers all of that.
Questions people ask

It puts thinking, speaking and learning into the area of friendship and hopes. Mercury brings thinking, talking and restlessness, concentrated in that department.
Is Mercury in the 11th house good or bad?

Yes. Houses are calculated from the degree rising on the eastern horizon, which changes every four minutes. Without a birth time there is no reliable house position at all.
What sign would my Mercury be in?
It depends on your rising sign. Using whole sign houses, your 11th house is the sign 10 places along from your rising sign. The table above lists all twelve.
