Yes, there is a difference between “Onto” and “On to”, in case you did not know. What the prepositions on and to mean when written together is actually different from what it implies when there’s a space in between.
The preposition onto means ‘upon’ – that is, to a place or position on; as used in the following sentences:
He threw his plate onto the floor.
The band climbed onto the stage.
It’s important to keep a distinction between the preposition onto and the use of the adverb on followed by the preposition to (meaning ‘onward and toward’). For example:
1. Let’s move onto the next point. (Let’s move upon the next point. This doesn’t make sense) WRONG
2. Let’s move on to the next point. CORRECT
3. Those who qualify can go onto college. (Those who qualify can go upon college. This doesn’t make sense too) WRONG
4. Those who qualify can go on to college. CORRECT.
