Awakens concern and unhappily resents it (9)
I believe the answer is:
interests
'awakens concern' is the definition.
I can't tell whether this definition defines the answer.
'unhappily resents it' is the wordplay.
'unhappily' indicates an anagram.
'resents'+'it'='resentsit'
'resentsit' is an anagram of 'INTERESTS'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for interests that I've seen before include "Pastimes or concerns" , "Pursuits of triteness" , "Hobbies or preoccupations" , "Advantages" , "Appeals, fascinates" .)
