Some gather at hers more willingly (6)
I believe the answer is:
rather
'more willingly' is the definition.
('I'd rather do this')
'some gather at hers' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'RATHER' is hidden in the letters of 'gather at hers'.
(Other definitions for rather that I've seen before include "Yes, please!" , "Pretty" , "Quite, sort of" , "Infinite time" , "To a certain extent" .)
