Acquire leverage (8)
I believe the answer is:
purchase
This clue is a double definition.
'acquire' is the first definition.
(I know that purchase is a type of acquire)
'leverage' is the second definition.
(I know that leverage can be written as purchase)
(Other definitions for purchase that I've seen before include "secure an advantage" , "Leverage" , "Acquire" , "become an owner" , "Procure" .)
