How Can I Insert a Description of Each Acronym on Each Form Question?

I have several questions on my form that use acronyms to avoid taking up too much space when the data is transferred to a spreadsheet.  How can I insert a description of each acronym by question?  The description would not need to show you on the spreadsheet.

Thanks.

P.S.

To clarify what I am looking for, I want to insert a sub label on a multiple choice question, but this option didn't appear under the question settings.

Hi there,

You can add "Hover text" to your fields. With that way, you can give more detailed information to users while the text doesn't take place on spreadsheet.

To add a "Hover text",

Select desired field and click to "Hover Text" button in the appeared toolbar. You can write your text in the generated text box.

Below, you can find the modified version of your cloned form:

If you stuck somewhere in the process, please let us know.

Thanks.
