Was banking made secure using pressure not force? (8)
I believe the answer is:
depended
'was banking' is the definition.
(to bank on something is to depend on it)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for depended that I've seen before include "Was conditional" , "Rested" , "Relied or hung on" .)
