What it means
You enjoy learning all your life — a second degree, courses, languages; philosophy, law and other cultures interest you. Explaining and teaching come out well.
The flip side is that there's more theory than practice in your words; arguments about views drag on.
This isn't about you if you don't need study after school and foreign languages don't come to you and don't interest you.
How to check it on yourself
Check it against your past — write your answer down before you look at the chart.
If your Mercury is in the 9th house
What should match. Recall the last ten years. At least one language, course or serious study was taken up of your own will, not because work required it.
When it’s not about you. Not one — this isn't about you.
