onto on to

Today we are going to take a closer look at how to use the similar sounding and looking words “onto” and “on to.” Misusing these words by interchanging them, as though they were the same thing, is a common mistake that even native speakers make. But hopefully after reading this post you will always know how to correctly use these words in your writing. So let’s see how “onto” and “on to” are used differently.

Onto – by definition this word means to be in a position “on” something, to be on top of, or upon. For example: He hopped onto the seat of his bike and rode away. Onto can also mean ‘fully aware of’ or ‘informed about.’ For example: The police were onto what the criminals planned to do next.

On to – the use of on to is the connection of the adverb “on” and the proposition “to” and belongs to a verbal phrase. For example: He held on to the handlebars of his bike as he rode.

The Chicago Manual of Style, which is a manual for how to properly write in English, gives the following hint to help you decide if you should use “onto” or “on to” if you are still stuck. Mentally say “up” before “on” and if the sentence still makes sense, then “onto” is probably the right choice. For example: He hopped (up) onto the seat of his bike and rode away – that works. He held (up) on to the handlebars of his bike as he rode – that doesn’t work.

Now, here is your chance to figure out which to use, “on to” or “onto.” Try this exercise to see how you do using the new information you learned above. Then scroll down to the answers below. Good luck!
