They are more conflicts arising while using In & On in a sentence. So I want to know some clarification regarding the usage of In & On in a sentence with a crystal clear example, because I'm in lot a confusion.
For Example:
I'm on train; In time; In tour.
I'm in train; On time; On tour.
My Question is : What is the meaning of in & on? where to use? how can we able to distinguish (Is there any rule, If available)?
Please do clarify me?
Note: I have gone through this. But have not get cleared still.
