Be enough to satisfy (7)
I believe the answer is:
suffice
This clue is a double definition.
'be enough' is the first definition.
(I've seen this before)
'satisfy' is the second definition.
(sufficing is a kind of satisfying)
'to' acts as a link.
(Other definitions for suffice that I've seen before include "Be adequate" , "Be enough" , "Serve - do" .)
