Turning out to be appropriate (8)
I believe the answer is:
becoming
I believe this is a double definition.
'turning out' is the first definition.
(I've seen this before)
'be appropriate' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for becoming that I've seen before include "Suitable; fitting" , "Looking good on; turning into" , "Turning into - lovely" , "Turning into; suiting" , "Undergoing a change" .)
