Interrogators make move, receiving directions to bug (7)
I believe the answer is:
gestapo
'interrogators make' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'move receiving directions to bug' is the wordplay.
'move' becomes 'go' (going is a kind of moving).
'receiving' is an insertion indicator.
'directions' becomes 'es' (east and south - two directions).
'to bug' becomes 'tap' ('tap' can be a synonym of 'bug').
'es'+'tap'='estap'
'go' going around 'estap' is 'GESTAPO'.
Can you help me to learn more?
(Other definitions for gestapo that I've seen before include "Notorious secret police" , "Hitler's secret police" , "Postage for Hitler's police" , "war force" , "Postage (anag)" .)
