Additional help (7)
I believe the answer is:
further
This clue is a double definition.
'additional' is the first definition.
('further' can be a synonym of 'additional')
'help' is the second definition.
(thesaurus)
(Other definitions for further that I've seen before include "In addition, also" , "More distant" , "To, or at, a greater extent, degree, or a more advanced stage" , "To somewhere more advanced" , "Moreover" .)
