Be grateful for rise in value (10)
I believe the answer is:
appreciate
I believe this is a double definition.
'be grateful' is the first definition.
(I've seen this in another clue)
'rise in value' is the second definition.
(I've seen this in another clue)
'for' is the link.
(Other definitions for appreciate that I've seen before include "Be grateful for - rise in value" , "Welcome" , "Grow in value" , "gain in value" , "Enjoy" .)
