Supply content for a French paper (5)
I believe the answer is:
equip
'supply' is the definition.
(I know that equip is a more specific form of the action supply)
'content for a french paper' is the wordplay.
'content for' says to take the centre.
'a french paper' becomes 'LEquipe' (L'Equipe is a French newspaper).
The centre of 'lequipe' is 'EQUIP'.
(Other definitions for equip that I've seen before include "Provide with items (for particular task)" , "Furnish with supplies" , "Give what's needed" , "Fit out, supply" , "Provide with requirements" .)
