Spared man, deployed sign (9)
I believe the answer is:
ampersand
'sign' is the definition.
(ampersand is a kind of sign)
'spared man deployed' is the wordplay.
'deployed' indicates an anagram.
'spared'+'man'='sparedman'
'sparedman' is an anagram of 'AMPERSAND'.
(Other definitions for ampersand that I've seen before include "Plus sign" , "Pens drama using &" , "that is seen at the keyboard" , "It connects" , "Character representing "and"" .)
