Bodyguard from concert hall embraced by tough guy (8)
I believe the answer is:
henchman
'bodyguard' is the definition.
(thesaurus)
'concert hall embraced by tough guy' is the wordplay.
'concert hall' becomes 'nch' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'embraced by' means one lot of letters goes inside another.
'tough guy' becomes 'heman' (I've seen this before).
'nch' inserted within 'heman' is 'HENCHMAN'.
'from' is the link.
Can you help me to learn more?
(Other definitions for henchman that I've seen before include "Follower of a criminal gang chief" , "Follower prepared to behave dishonestly" , "Faithful helper" , "Faithful attendant" , "abettor in crime?" .)
