Satisfies Tessa, perhaps (5)
I believe the answer is:
sates
'satisfies' is the definition.
(I've seen this in another clue)
'tessa perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'tessa' is an anagram of 'SATES'.
(Other definitions for sates that I've seen before include "Stuffs or cloys with excess" , "Gluts or cloys with excess" , "Fully satisfies" , "Satisfies -- asset (anag)" , "Fills to satisfaction" .)
