Their Mercury in your 11th house

They trade ideas with your friends

In synastry, you place one person's planets into the other person's houses. When someone's Mercury, how you think, falls in your 11th house, Circle, that part of them shows up in the part of your life about friends, community, future goals.

What it's like

Group chats, a shared newsletter, a plan hatched at someone's birthday. This person connects conversations, and your goals feel more real once they've been talked through.

The good

They bring good ideas into your circle

The tension

Talk can outrun any plan actually made

It depends who they are

The same placement plays out differently with a partner, an ex or your mum.

If they're your partner

They trade ideas with your friends

This person turns up to your friends' dinners with opinions and questions. Their chat is welcome, though your friends may know them better than you expected.

If they're a crush

They bring you into the group chat

Conversation with this person drifts to friends, plans and shared interests. They may feel like both a crush and a mate.

If they're an ex

They were chatty in your crowd

This person got on with your friends and turned up in your group chats. Reaching a friendly, light tone matters now, and is usually easiest in writing.

If they're a friend

They link you with the right people

This person always knows someone who knows someone. They fill your circle with chatter and introductions, plus group chats you may regret joining.

If they're family

They pass on news and plans

This person knows who is doing what and tells you in detail. They keep you in the loop on friends, relatives and the wider gossip.

The other way round: Your Mercury in their 11th house
