Which is more appropriate and why (while travelling in a lift)?
I am in the moving lift.
I am on the moving lift. (on the surface of the lift, it can be top or bottom which is meaningless)
I am inside the moving lift.(Same meaning as in)
"I am in the moving lift." is the most appropriate. It means you are inside the lift while heading for your room/office upstaires. If the lift stops moving, you say: I was trapped in (not on) the lift,
