How can I create a fillable text box within a sentence?

Im trying to copy my insurance waiver that looks like this:

I, _______________________________, have read the below information and initialed each section to indicate that I fully understand what to expect. If I have any questions or concerns, I will address these with my skin therapist. I give permission to my skin therapist, ________________________, 

Is there a way to make a fillable text box where the blank underlined area is?

Thnak you!

You can use the Narrative Field widget in order to achieve this type of function. Please check this demo form. 

Hope that helps. Thank you.
