Sharing gives ad-hoc read access to other users. You can choose individual users to share with.

Let's say there are users who have edit rights only. If you share a form with them, these users who have edit rights but not read access will be able to edit after you have shared with them. Those who are shared with are called participants.

To put it simply, you can share a form with other users to give them permission to see the form(s). (You will need "Share" permissions to perform the "Share" action).
