"A Christmas Carol” character (4,3)
I believe the answer is:
tiny tim
'a christmas carol character' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for tiny tim that I've seen before include "Lovable boy in Dickens novel ` `A Christmas Carol' '" , "Poor little kid" , "Invalid 16 [CRATCHIT]" , "Dickens mite" , "Cratchit's youngest (C. Carol)" .)
