Restrain fellow fighter pilot capturing head of Luftwaffe? (7)
I believe the answer is:
manacle
'restrain' is the definition.
(thesaurus)
'fellow fighter pilot capturing head of luftwaffe?' is the wordplay.
'fellow' becomes 'man' (I've seen this before).
'fighter pilot' becomes 'ace' (I've seen this before).
'capturing' is an insertion indicator.
'head of' suggests taking the first letters.
The initial letter of 'luftwaffe' is 'l'.
'ace' enclosing 'l' is 'acle'.
'man'+'acle'='MANACLE'
(Other definitions for manacle that I've seen before include "Hand/ankle restraint" , "Metal shackle" , "item restricting movement" , "Curb" , "Handcuff" .)
