Small sculpture of ET breaks the law (9)
I believe the answer is:
statuette
'small sculpture' is the definition.
(I've seen this before)
'et breaks the law' is the wordplay.
'breaks' is an insertion indicator (inserted letters break into the word).
'the law' becomes 'statute' (I've seen this before).
'et' going within 'statute' is 'STATUETTE'.
'of' is the link.
(Other definitions for statuette that I've seen before include "Small sculpture" , "Small figure's" , "Figurine, a small carving" , "Small carved or moulded figure" .)
