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 more specific form 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" .)
