The prepositions in/into and on/onto are often confused by students learning English. The explanation is quite easy, though. Let’s take a look.
In / Into
In is used when something is already located inside of something, for example:
The book is in the backpack.
The students are in the room, waiting for the teacher.
Into, however, is used when there is movement from the outside to inside, for example:
He put the books into the backpack. (The book were originally outside the backpack.)
The students went into the room to wait for the teacher. (They were outside the room.)
Similarly, on is used when the thing or person is already located something, for example:
The phone is on the table.
There’s a monkey on my car.
Onto, similar to into, is used when there is movement to the surface or place, for example:
I moved the phone onto the table.
The monkey jumped onto my car.
