Fellow is hesitantly nurturing dreams (6)
I believe the answer is:
wishes
'dreams' is the definition.
(I've seen this in another clue)
'fellow is hesitantly nurturing' is the wordplay.
'nurturing' indicates a hidden word.
'WISHES' can be found hidden inside 'fellow is hesitantly'.
(Other definitions for wishes that I've seen before include "Desires, hopes" , "Wills, wants" , "''If . . . . . . were horses, beggars would ride'' (6)" .)
