Make nervous actors on the perimeter (3,2,4)
I believe the answer is:
set on edge
'actors on the perimeter' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'make nervous' is the wordplay.
'make' becomes 'set' (setting is a kind of making).
'nervous' becomes 'on edge' (on edge can mean nervous or tense).
'set'+'onedge'='SET ON EDGE'
Can you help me to learn more?
(Other definitions for set on edge that I've seen before include "Excite" , "stirred" .)
