Large piece, lump (4)
I believe the answer is:
hunk
This clue is a double definition.
'large piece' is the first definition.
(I've seen this in another clue)
'lump' is the second definition.
(I know that lump can be written as hunk)
(Other definitions for hunk that I've seen before include "Lump - beefcake" , "Macho man" , "Rough piece; attractive man (slang)" , "Well-built sexually attractive man" , "Large lump - piece" .)
