Leaves summons (5)
I believe the answer is:
pages
I believe this is a double definition.
'leaves' is the first definition.
(leaf can mean a page)
'summons' is the second definition.
(paging is a kind of summoning)
(Other definitions for pages that I've seen before include "Book leaves" , "Boy attendants" , "Sheets of a book" , "Young attendants" , "Hotel employees" .)
