Provide, fit out (5)
I believe the answer is:
equip
This clue is a double definition.
'provide' is the first definition.
(equipping is a kind of providing)
'fit out' is the second definition.
(I know that fit out can be written as equip)
(Other definitions for equip that I've seen before include "Supply (with items)" , "Supply with what is needed" , "Provide everything that is required'" , "Accoutre" , "Provide stuff" .)
