See increase (10)
I believe the answer is:
appreciate
I believe this clue is a double definition.
'see' is the first definition.
(appreciating is a kind of seeing)
'increase' is the second definition.
(appreciating is a kind of increasing)
(Other definitions for appreciate that I've seen before include "(Of asset) rise in value" , "See < prize" , "gain in value" , "Grow in value" , "increase in price" .)
