In flexible way making provision (6)
I believe the answer is:
supply
I believe this clue is a double definition.
'in flexible way' is the first definition.
(I've seen this before)
'provision' is the second definition.
(synonyms)
'making' acts as a link.
(Other definitions for supply that I've seen before include "Give" , "Teacher, sort of" , "in pliant manner" , "Furnish goods or services" , "Contribute" .)
