Summary:

This resource explains the uses of the preposition, "onto."

Uses of "Onto"

"Onto" can generally be replaced by "on" with verbs of motion.


This image shows a hat on a man's head.

The hat went on(to) his head.

Here are some more examples:

Some verbs of motion express the idea that the subject causes itself or some physical object to be situated in a certain place (compare the three example directly above).
Of these verbs, some take only "on". Others take both on and onto, with the latter being preferred by some speakers.

This image shows socks on a person's feet.

He put the socks on his feet.

Here are some more examples:

Verbs taking only "on" are rare: set may be another one, and so perhaps is put. Other verbs taking both prepositions are raise, scatter (when it takes a direct object), pour, and add.

In "We're adding on a wing at the back of the building" on is really part of the verb, while in "We're adding a porch onto the house" onto is a simple preposition. This contrast points to a fairly important and general rule:

Simple prepositions can combine with verbs, but compound prepositions cannot.

Note also that in "The farmer scattered seed on(to) the fertile ground", the word "on" has its ordinary meaning of a position on a surface, but in this case the surface is vertical rather than horizontal— the side of a building.

There are a number of verb-preposition combinations which are formally like "add on" but have the meaning "of continuing or resuming an action" when used in the imperative mood.

Except for hang, which takes both on and onto, they all occur only with on. The meanings of these combinations, some of which are idiomatic, are given in parentheses. Not all of them have the force of a command.

Drive on! (Or, Keep driving toward the city).
