Provide — flexibility (4)
I believe the answer is:
This clue is a double definition.
'provide' is the first definition.
(I know that provide is a more specific form of the action give)
'flexibility' is the second definition.
(I've seen this in another clue)
(Other definitions for give that I've seen before include "Donate or hand over" , "Donate, grant" , "Yield - supply" , "be generous?" , "Yield, produce" .)
