What Is Their Main Difference?
The main difference between 'on' and 'onto' is in the meaning they convert. 'On' is used to talk about location and motion while 'onto' is used to talk only about motion and direction.
Talking about Location
When we want to talk about the location of something that is vertically at a higher position and in contact with the surface of the lower object.
My bag is
I left the bottle
Talking about Motion
Both 'on' and 'onto' can be used to show motion and direction. Have a look:
She drove her baby stroller
She drove her baby's stroller
State verbs cannot be used with 'onto.' State verbs do not refer to an action and therefore cannot help representing motions. Take a look at the following examples:
onto his way.
There are state verbs that are used with 'onto' to create idiomatic phrases and sentences. Such as:
