Doris can hurt, being scornful (8)
I believe the answer is:
sardonic
'scornful' is the definition.
(I've seen this before)
'doris can hurt' is the wordplay.
'hurt' indicates an anagram.
'doris'+'can'='doriscan'
'doriscan' anagrammed gives 'SARDONIC'.
'being' is the link.
(Other definitions for sardonic that I've seen before include "Sarcastic" , "Scornfully mocking" , "Disdainfully or ironically humorous" , "Derisively ironic" , "Dry, cynically mocking" .)
