Admire increase in price (10)
I believe the answer is:
appreciate
I believe this is a double definition.
'admire' is the first definition.
(thesaurus)
'increase in price' is the second definition.
(I've seen this before)
(Other definitions for appreciate that I've seen before include "Increase in value" , "Grow in value" , "increase in price" , "See < prize" , "Be grateful for - rise in value" .)
