Service from graduate isn't fantastic (6)
I believe the answer is:
matins
'service' is the definition.
(I've seen this before)
'graduate isn't fantastic' is the wordplay.
'graduate' becomes 'ma' (abbreviation for Master of Arts**).
'fantastic' indicates anagramming the letters.
'isnt' with letters rearranged gives 'tins'.
'ma'+'tins'='MATINS'
'from' acts as a link.
(Other definitions for matins that I've seen before include "Isn't ma given to morning prayers?" , "C of E's daily morning service" , "Church service" , "Morning prayers or bird-songs" , "Anglican morning service" .)
