It's short notice to take exam again turning up for job in promotions (10)
I believe the answer is:
advertiser
'job in promotions' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'it's short notice to take exam again turning up' is the wordplay.
'it's short' means to remove the last letter.
'notice' becomes 'advert' (I have seen 'Public notice ' mean 'advert' so perhaps 'notice' could also mean 'advert').
'to take exam again' becomes 'resit' (I've seen this before).
'turning up' shows that the letters should be reversed in order.
'resit' back-to-front is 'tiser'.
'advert' with its last letter taken off is 'adver'.
'adver'+'tiser'='ADVERTISER'
'for' is the link.
Can you help me to learn more?
(Other definitions for advertiser that I've seen before include "He pushes" , "Part of a newspaper's title" , "Publicist" , "One who can use multiple media" , "Promoter" .)
