Snatch crust of bread during sale (9)
I believe the answer is:
abduction
'snatch' is the definition.
(thesaurus)
'crust of bread during sale' is the wordplay.
'crust of' says to hollow out the word (remove centre letters) (the external letters or crust of the word).
'during' is an insertion indicator.
'sale' becomes 'auction' (public sale).
'bread' with its middle removed is 'bd'.
'bd' placed inside 'auction' is 'ABDUCTION'.
(Other definitions for abduction that I've seen before include "Kidnapping" , "forcible removal" , "Carrying off (of a person)" .)
