All __; ready
I believe the answer is:
set
This clue is a double definition.
'all' is the first definition.
(thesaurus)
'ready' is the second definition.
(I know that ready can be written as set)
(Other definitions for set that I've seen before include "Group; hard" , "Where they're filming" , "Major segment of tennis match" , "Become stiff like jelly" , "Mount (precious stone)" .)
