Letter card (9)
I believe the answer is:
character
I believe this clue is a double definition.
'letter' is the first definition.
(I've seen this before)
'card' is the second definition.
(thesaurus)
(Other definitions for character that I've seen before include "card" , "Person in a play; letter" , "Nature; good reputation" , "Personal moral qualities" , "crank" .)
