Where stockholders make a killing? (8)
I believe the answer is:
abattoir
'where stockholders make a killing?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for abattoir that I've seen before include "it makes a killing" , "It might make a killing" , "scene of slaughter" , "Animal slaughter-house" , "shambles once" .)
