Works for internal developer at estate (8)
I believe the answer is:
operates
'works' is the definition.
(I know this)
'internal developer at estate' is the wordplay.
'OPERATES' is hidden within the letters.
But, I am uncertain how this is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for operates that I've seen before include "Acts" , "Directs or controls, machinery say" , "[TREAT] s with a knife" , "'Uses, manipulates (8)'" , "Functions" .)
