Like Autumn leaves, oddly white and red (8)
I believe the answer is:
withered
'like autumn' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'oddly white and red' is the wordplay.
'oddly' is an anagram indicator.
'and' is a charade indicator (letters next to each other).
'white' anagrammed gives 'withe'.
'withe'+'red'='WITHERED'
'leaves' is the link.
Can you help me to learn more?
(Other definitions for withered that I've seen before include "Dried and shrivelled up" , "declined" , "like Keats's sedge?" , "Having lost all moisture, vegetation, say" , "Lost freshness and dried up" .)
