Mercury in Sagittarius meaning
Mercury in Sagittarius thinks big. You are drawn to the meaning behind things, the wider view, the idea that connects a lot of smaller ideas, and the small print tends to bore you. Optimism runs through your thinking, and you are usually sure the answer is out there somewhere just past the horizon.
You communicate with candor and enthusiasm, and your bluntness is rarely unkind, just unfiltered. You would rather be honest than smooth. The tradeoff is that in your rush toward the big point you can skip the details, promise a bit more than fits, or generalize where precision was needed.
You learn through exploration: travel, new philosophies, conversations with people unlike you. This Mercury studies best when a subject opens a door to something larger, and it stays curious long after the classroom would have let it go.
