Charlie with bone china defect? (4)
I believe the answer is:
chip
'china defect?' is the definition.
(I've seen this in another clue)
'charlie with bone' is the wordplay.
'charlie' becomes 'C' (phonetic alphabet).
'with' is a charade indicator (letters next to each other).
'bone' becomes 'hip' ().
'c'+'hip'='CHIP'
(Other definitions for chip that I've seen before include "Off the old block, he's junior" , "High ball" , "Crack" , "Roulette counter" , "Flaw" .)
