Setters put through tests bound for hard work here (9)
I believe the answer is:
sweatshop
'hard work here' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'setters put through tests bound' is the wordplay.
'setters' becomes 'we' (I can't explain this - if you can you should believe this answer much more).
'put through' is an insertion indicator.
'tests' becomes 'sats' (american school tests).
'bound' becomes 'hop' (I've seen this in another clue).
'we' inserted within 'sats' is 'sweats'.
'sweats'+'hop'='SWEATSHOP'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for sweatshop that I've seen before include "Exploitative factory" , "Place where long hours are worked for low pay" , "where work is hard" , "Factory using underpaid labour" , "Factory (derog.)" .)
