Aggravated, annoyed? It's innocuous (7)
I believe the answer is:
anodyne
'innocuous' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'aggravated annoyed?' is the wordplay.
'aggravated' indicates an anagram.
'annoyed' is an anagram of 'ANODYNE'.
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for anodyne that I've seen before include "Bland and inoffensive" , "Analgesic; bland" , "Harmless, bland" , "painkiller" , "Pain relieving" .)
