Manage publicity initially required in small country? (12)
I believe the answer is:
administrate
'manage' is the definition.
(administrating is a kind of managing)
'publicity initially required in small country?' is the wordplay.
I cannot really see how this works, but
'publicity' could be 'ad' (advert) and 'ad' is present in the answer.
'in' is present in the answer.
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is located in the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for administrate that I've seen before include "Organise (business)" , "direct" , "Manage - it's marinated (anag)" , "Run" .)
