How would you usability test wording of an action?

We're designing a portal where users can create pages with content. One piece of content is 'embedding' something like a form or document into the page.

The term 'embed' has been confusing in usability tests so far, so I want to create a test specifically around which word would make sense to people.

Has anyone created a test like this? If so, how do you best test for this scenario?

My plan so far is explaining the action then giving users a series of words where they pick the one that makes the most sense to them.
