One's work here should bear fruit (7)
I believe the answer is:
orchard
'here should bear fruit' is the definition.
I know that 'fruit' relates to this answer. I also know that both the answer and definition are singular nouns
'one's work' is the wordplay.
'one's' becomes 'orc' (I am not sure about this - if you are sure you should believe this answer much more).
'work' becomes 'hard' (hard work is a kind of work).
'orc'+'hard'='ORCHARD'
(Other definitions for orchard that I've seen before include "Plot for fruit trees" , "Land planted with fruit trees" , "Plantation of fruit trees" , "Cultivated land" , "Clump of fruit trees" .)
