Mercury in Sagittarius
Mercury is in detriment in Sagittarius: the mind is broad, opinionated and better at the big picture than at the detail. It thinks in principles and speaks with conviction; tact is not its first instinct. This is a placement for teaching, publishing and travel — anywhere meaning matters more than precision. The work is to check the facts before the sermon.
In plain words
Mercury stands for how you think and talk. In Sagittarius, that works in a Sagittarius way: upbeat, blunt and always looking further. You say what you think and want to see what is over the hill.
