Form of restraint possibly making lad choke? (8)
I believe the answer is:
headlock
'form of restraint' is the definition.
(I've seen this before)
'making lad choke?' is the wordplay.
'making' indicates an anagram.
'lad'+'choke'='ladchoke'
'ladchoke' is an anagram of 'HEADLOCK'.
'possibly' acts as a link.
(Other definitions for headlock that I've seen before include "Wrestling hold" , "Grip" , "A way to control" , "Form of restraint" .)
