Exhibits case of rare gifts (10)
I believe the answer is:
represents
'exhibits' is the definition.
The answer and definition can be both to do with fundamental existence as well as being verbs in their -s form.
Perhaps you can see a link between them that I don't see?
'case of rare gifts' is the wordplay.
'case of' means to remove the middle letters (like emptying a case).
'gifts' becomes 'presents' ('present' can be a synonym of 'gift').
'rare' with its centre removed is 're'.
're'+'presents'='REPRESENTS'
Can you help me to learn more?
(Other definitions for represents that I've seen before include "Stands for" , "Portrays" , "shows" , "plays" .)
