Master move in current production (6)
I believe the answer is:
stream
'current production' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'master move' is the wordplay.
'move' indicates anagramming the letters.
'master' is an anagram of 'STREAM'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for stream that I've seen before include "Flow of water on land" , "group of schoolchildren" , "Brook or rivulet" , "selected pupils" , "'Brook, runnel (6)'" .)
