Furnish, provide (6)
I believe the answer is:
supply
I believe this is a double definition.
'furnish' is the first definition.
(I know that furnish can be written as supply)
'provide' is the second definition.
(I know that provide can be written as supply)
(Other definitions for supply that I've seen before include "in flexible way" , "in a compliant manner" , "Contribute" , "Fund" , "Provide or furnish with" .)
