Soldier hardly gregarious? (7)
I believe the answer is:
private
'soldier' is the definition.
(private is a type of soldier)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for private that I've seen before include "(Of a place) secluded" , "Soldier; personal" , "Clandestine" , "Secret - serviceman" , "One's own" .)
