Shiny sets redesigned to provide harmony (9)
I believe the answer is:
synthesis
'harmony' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'shiny sets redesigned' is the wordplay.
'redesigned' indicates anagramming the letters.
'shiny'+'sets'='shinysets'
'shinysets' is an anagram of 'SYNTHESIS'.
'to provide' acts as a link.
Can you help me to learn more?
(Other definitions for synthesis that I've seen before include "Result of combining" , "Chemical or dialectical blending process" , "process of combining ideas" , "Fusion" , "getting together tricky" .)
