Unfinished direction about Public Relations growth (6)
I believe the answer is:
sprout
'growth' is the definition.
(I've seen this before)
'unfinished direction about public relations' is the wordplay.
'unfinished' means to remove the last letter.
'direction' becomes 'south' (compass direction).
'about' is an insertion indicator.
'public relations' becomes 'PR' (abbreviation).
'south' with its last letter taken off is 'sout'.
'sout' placed around 'pr' is 'SPROUT'.
(Other definitions for sprout that I've seen before include "Put forth shoots" , "Spring up like vegetable from Brussels" , "Develop new growth" , "something for Christmas dinner?" , "Produce new growth" .)
