Welcome to the Theatre Dictionary’s conversation about the term off-book.

On off-book’s official page, we define the term as “when actors don’t have to refer to a script since they’ve completely memorized their lines.” But now we want to know what the term off-book means to you. You can use the comments section to tell us.

— Do you have any tricks for memorizing lines?

— Did you ever think you were off-book only to find that the slightest distraction caused you to forget your lines?

— Have you ever seen a professional actor go up on his or her lines? What happened and how did the performer recover?

If you’d like to make a video of your own about the term off-book, then we’d love to hear from you! Just email us through our contact page. Tell us about yourself and why you want to make a video. We’ll be in touch ASAP and give you details on how to add your video to the Theatre Dictionary!

Cheers,

Mark Blankenship, Theatre Dictionary editor
