Student or Learner
The setting is the conversation I had with my friend about the investment he has made for some time. When I asked him if he is still doing the investment thing in the stock market, what preposition do I use between "in" and "on"?
My question goes like " Are you still on it (=investment thing)?
Please let me know if "on" in above sentence needs to be changed into "in" or if that is still okay.
Thank you in advance.
