Heavenly chips are chopped up (8)
I believe the answer is:
seraphic
'heavenly' is the definition.
(thesaurus)
'chips are chopped up' is the wordplay.
'chopped up' indicates an anagram.
'chips'+'are'='chipsare'
'chipsare' anagrammed gives 'SERAPHIC'.
(Other definitions for seraphic that I've seen before include "Like the highest ofder of angels" , "serene" , "To do with top angels" , "Angelic" .)
