Outfit with flexibility (6)
I believe the answer is:
supply
This clue is a double definition.
'outfit' is the first definition.
(thesaurus)
'with flexibility' is the second definition.
(I've seen this before)
(Other definitions for supply that I've seen before include "store" , "Teacher, sort of" , "in a compliant manner" , "Furnish goods or services" , "Fund" .)
