Publicity specialist who revised a lot of mandates (5)
I believe the answer is:
adman
'of mandates' is the definition.
The definition suggests a singular noun which matches the answer.
'publicity specialist who revised a lot' is the wordplay.
I cannot quite understand how this works, but
'publicity' could be 'ad' (short for advert) and 'ad' is found within the answer.
'a' could be 'an' and 'an' is present in the answer.
'lot' could be 'm' and 'm' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for adman that I've seen before include "Commercial publicist" , "Worker in commercials" , "promoter" , "persuasive type" , "Someone involved in commercial promotion" .)
