The war affected some flowers (6)
I believe the answer is:
wreath
'the war affected some flowers' is the definition.
I can't tell whether this defines the answer.
'the war affected' is the wordplay.
'affected' indicates anagramming the letters.
'the'+'war'='thewar'
'thewar' with letters rearranged gives 'WREATH'.
Can you help me to learn more?
(Other definitions for wreath that I've seen before include "Circular band, of flowers say" , "Flower arrangement" , "Festive garland" , "Circular band of flowers and leaves, often seen on graves" , "Circle of flowers for mourning" .)
