Letter or card (9)
I believe the answer is:
character
I believe this is a double definition.
'letter' is the first definition.
(written character)
'card?' is the second definition.
(I've seen this before)
'or' acts as a link.
(Other definitions for character that I've seen before include "Sign" , "Role - nature" , "crank" , "Letter or number" , "Amusing individual" .)
