An extraordinary deed or act may get you this (9)
I believe the answer is:
decorated
'get you this' is the definition.
The definition suggests a singular noun but the answer is not.
'an extraordinary deed or act' is the wordplay.
'an extraordinary' indicates an anagram.
'deed'+'or'+'act'='deedoract'
'deedoract' anagrammed gives 'DECORATED'.
'may' is the link.
Can you help me to learn more?
(Other definitions for decorated that I've seen before include "like a warrior?" , "Wallpapered" , "Awarded medal(s)" , "Ornate" , "Adorned, bedecked" .)
