Struggling sorting out added VAT gains (13)
I believe the answer is:
disadvantaged
'struggling' is the definition.
Both the answer and definition are adjectives. Perhaps you can see an association between them that I can't see?
'sorting out added vat gains' is the wordplay.
'sorting out' indicates an anagram.
'added'+'vat'+'gains'='addedvatgains'
'addedvatgains' with letters rearranged gives 'DISADVANTAGED'.
Can you help me to learn more?
(Other definitions for disadvantaged that I've seen before include "Socially or economically deprived" , "In deprived circumstances" , "Handicapped" , "Put in an unfavourable position" , "In unfavourable circumstances" .)
