Sample sentence: "What is your favorite bookstore?"
= "YOUR FAVORITE BOOKSTORE, what-NAME?"
In the sentence example above, I use an almost imperceptible second movement on
the sign BOOK.
Most of the time you can just open the hands once and people will know that
you are referring to a book. Technically, the sign BOOK is a noun/verb pair. If you use a double motion it means
book. If you use a single motion it means "open book." If
you reverse the motion by starting with the hands open and then closing
them, it means "close the book" or "close your books."
