Swindle nets £1,000 case of Armagnac brandy (6)
I believe the answer is:
cognac
'brandy' is the definition.
(Cognac is an example)
'swindle nets ps1000 case of armagnac' is the wordplay.
'swindle' becomes 'con' (synonyms).
'nets' indicates putting letters inside.
'psg000' becomes 'g' (I can't justify this - if you can you should believe this answer much more).
'case of' says to hollow out the word (remove centre letters) (outsides of).
'armagnac' with its centre taken out is 'ac'.
'con' enclosing 'g' is 'cogn'.
'cogn'+'ac'='COGNAC'
Can you help me to learn more?
(Other definitions for cognac that I've seen before include "Good brandy" , "Liquor" , "strong drink" , "Brandy as for Napoleon (6)." , "French brandy region" .)
