Acquire grip? (8)
I believe the answer is:
purchase
I believe this is a double definition.
'acquire' is the first definition.
(purchasing is a kind of acquiring)
'grip?' is the second definition.
(thesaurus)
(Other definitions for purchase that I've seen before include "Pay money" , "Obtain in return for payment" , "firm grasp" , "Shop successfully" , "Spend some money" .)
