Sacrifice strong in foreign parts (8)
I believe the answer is:
offering
'sacrifice' is the definition.
(eg an offering to a god)
'strong in foreign parts' is the wordplay.
'strong' becomes 'f' (musical symbol for 'forte', 'strong' in Italian).
'in' means one lot of letters goes inside another.
'parts' indicates anagramming the letters (the parts of the original word ordered differently).
'foreign' anagrammed gives 'ofering'.
'f' put within 'ofering' is 'OFFERING'.
(Other definitions for offering that I've seen before include "Oblation" , "Money contributed at a religious service" , "making a bid" , "Sacrifice to deity" , "Tendering - sacrifice" .)
