Name boy in 'Loot' in final performance (8)
I believe the answer is:
swansong
'final performance' is the definition.
(I've seen this before)
'name boy in loot' is the wordplay.
I cannot quite see how this works, but
'name' could be 'n' (common abbreviation e.g. on forms) and 'n' is found within the answer.
'boy' could be 'son' (synonyms) and 'son' is present in the answer.
'loot' could be 'swag' (synonyms) and 'swag' is found within the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for swansong that I've seen before include "last performance" , "Last call" , "Final appearance" , "Final work or performance" , "Last act" .)
