Watch your step or you _____ trip.
Which is correct? And why?
I would also say "might" in that sentence.
I found a website that has a very good explanation of how to choose "may" or "might". I hope you will find the website helpful. If you still have questions after reading it, feel free to ask me.
"May" also seems correct, but it sounds more formal to me and I wouldn't use it.
I could be wrong. Hope this helped.
Hinative.com will help you is this case.
Is "Trip" here means Slip?
