Plunder Isolde redistributed, being soft-hearted (7)
I believe the answer is:
despoil
'plunder' is the definition.
(I know that plunder can be written as despoil)
'isolde redistributed being soft-hearted' is the wordplay.
I cannot quite understand how this works, but
'soft' could be 'p' (musical abbreviation for 'piano') and 'p' is present in the answer.
an anagram of 'isolde' is 'desoil' which is located in the left over letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for despoil that I've seen before include "Plunder - I sloped (anag)" , "Plunder, devastate" , "Plunder - piled so (anag)" , "sack" , "Ravage" .)
