Polish people news boss brings in (5)
I believe the answer is:
emend
'polish' is the definition.
(I've seen this in another clue)
'people news boss brings in' is the wordplay.
I cannot quite understand how this works, but
'people' could be 'men' (men are people) and 'men' is found within the answer.
'boss' could be 'ed' (short for editor - newspaper boss) and 'ed' is found within the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for emend that I've seen before include "Make correction in written material" , "Improve by altering" , "Edit; make alterations to a draft" , "Remove errors" , "Modify" .)
