Manager’s job could be a sight more powerful (11)
I believe the answer is:
supervision
'manager's job' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'a sight more powerful' is the wordplay.
I cannot really see how this works, but
'a' could be 'per' (eg 'one a day' means 'one per day') and 'per' is found in the answer.
'sight' could be 'vision' (synonyms) and 'vision' is found in the answer.
This explanation may well be incorrect...
'could be' is the link.
Can you help me to learn more?
(Other definitions for supervision that I've seen before include "Oversight" , "Control" , "provided by the boss" .)
