Men chatted casually, not getting involved (10)
I believe the answer is:
detachment
'not getting involved' is the definition.
I can't judge whether this defines the answer.
'men chatted casually' is the wordplay.
'casually' indicates anagramming the letters (I've seen this in other clues).
'men'+'chatted'='menchatted'
'menchatted' with letters rearranged gives 'DETACHMENT'.
Can you help me to learn more?
(Other definitions for detachment that I've seen before include "some engaged in military action?" , "Coolness - body of troops" , "squad" , "Unit of soldiers" , "Military unit" .)
