Piece right, apart from clasps (7)
I believe the answer is:
excerpt
'piece' is the definition.
(I have seen 'Piece of work' mean 'excerpt' so perhaps 'piece' could also mean 'excerpt')
'right apart from clasps' is the wordplay.
'right' becomes 'r' (common abbreviation).
'apart from' becomes 'except' (I've seen this before).
'clasps' means one lot of letters goes inside another.
'r' going within 'except' is 'EXCERPT'.
(Other definitions for excerpt that I've seen before include "Short extract" , "A passage or quotation from" , "Piece selected from a film" , "Passage taken from book etc" , "newspaper clipping" .)
