Bring round article held by apple grower (4)
I believe the answer is:
coax
'bring round' is the definition.
(to coax someone is to bring them around)
'article held by apple grower' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'held by' means one lot of letters goes inside another.
'apple grower' becomes 'cox' (Cox apples were first cultivated by Richard Cox).
'a' put within 'cox' is 'COAX'.
(Other definitions for coax that I've seen before include "Persuade; type of cable" , "Gradually persuade (someone)" , "sort of cable" , "attempt to influence" , "Inveigle" .)
