Grasp treasure (10)
I believe the answer is:
appreciate
I believe this is a double definition.
'grasp' is the first definition.
(thesaurus)
'treasure' is the second definition.
('appreciate' can be a synonym of 'treasure')
(Other definitions for appreciate that I've seen before include "Treasure" , "Take full account of" , "See < prize" , "Enjoy" , "prize > increase" .)
