Book performances (4)
I believe the answer is:
acts
I believe this is a double definition.
'book' is the first definition.
(I've seen this before)
'performances' is the second definition.
(act is a kind of performance)
(Other definitions for acts that I've seen before include "NT book; laws" , "Cast down by deeds" , "Is effective" , "bands, comedians, etc" , "Deeds or play segments" .)
