Current policy will enhance efficiency (10)
I believe the answer is:
streamline
'enhance efficiency' is the definition.
I can't judge whether this definition defines the answer.
'current policy' is the wordplay.
'current' becomes 'stream' (synonyms).
'policy' becomes 'line' (the party line is a party's policy on something).
'stream'+'line'='STREAMLINE'
'will' acts as a link.
Can you help me to learn more?
(Other definitions for streamline that I've seen before include "run things more efficiently" , "Increase efficiency" , "make more efficient" , "Smooth" , "eliminate resistance" .)
