Cherish rise in value (10)
I believe the answer is:
appreciate
This clue is a double definition.
'cherish' is the first definition.
(thesaurus)
'rise in value' is the second definition.
(I've seen this before)
(Other definitions for appreciate that I've seen before include "Grow in value" , "Enjoy" , "Treasure" , "increase in price" , "Take full account of" .)
