Genius present (4)
I believe the answer is:
gift
I believe this clue is a double definition.
'genius' is the first definition.
(thesaurus)
'present' is the second definition.
('gift' can be a synonym of 'present')
(Other definitions for gift that I've seen before include "A present or gratuity" , "A present or a natural ability" , "Present - natural aptitude" , "bent" , "Special aptitude - present" .)
