Landlords character (6)
I believe the answer is:
letter
'character' is the definition.
(I know that letter is a type of character)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for letter that I've seen before include "he leases" , "Unit of alphabet" , "Piece of correspondence" , "Communication via the postman" , "Epistle, missive" .)
