Leverage needed for acquisition (8)
I believe the answer is:
purchase
I believe this is a double definition.
'leverage' is the first definition.
(I've seen this before)
'for acquisition' is the second definition.
(purchase is a kind of acquisition)
'needed' acts as a link.
(Other definitions for purchase that I've seen before include "secure an advantage" , "Shop successfully" , "Acquisition" , "Procure" , "Made" .)
