Fitting grand, you see ultimately (3)
I believe the answer is:
due
'fitting' is the definition.
(both can mean appropriate)
'grand you see ultimately' is the wordplay.
'ultimately' says to take the final letters.
The last letters of 'grand you see' are 'DUE'.
(Other definitions for due that I've seen before include "Unpaid or expected" , "Rightful" , "Expected; proper" , "Expected; appropriate" , "Proper; owed" .)
