Contribute in nimble manner (6)
I believe the answer is:
supply
I believe this is a double definition.
'contribute' is the first definition.
(I've seen this before)
'in nimble manner' is the second definition.
(in a supple way)
(Other definitions for supply that I've seen before include "with considerable flexibility" , "Provide; flexibly" , "in pliant manner" , "Stand-in teacher" , "Furnish goods or services" .)
