Fig or olive (4)
I believe the answer is:
tree
This clue is a double definition.
'fig' is the first definition.
(thesaurus)
'olive' is the second definition.

(Other definitions for tree that I've seen before include "Elder, possibly" , "Plant with bark" , "eg Ash, oak" , "eg Lime" , "Genealogy chart" .)
