Origins, heritage (5)
I believe the answer is:
roots
This clue is a double definition.
'origins' is the first definition.
('root' can be a synonym of 'origin')
'heritage' is the second definition.
(I've seen this in another clue)
(Other definitions for roots that I've seen before include "Nerve endings" , "Underground growths" , "Supports" , "Beginnings, origins" , "Genealogy" .)
