I believe the answer is:
tim
(Other definitions for tim that I've seen before include "Tiny . . . is a lovable small boy from Dickens" , "Tiny . . . is a loveable Dickens boy" , "- Rice, musical lyricist" , "-- Brooke-Taylor, comedian; -- Minchin, comedian" , "Tiny -, Dickens character (A_Christmas Carol)" .)
