The list shows a national emblem (7)
I believe the answer is:
thistle
'a national emblem' is the definition.
(emblem of Scotland)
'the list' is the wordplay.
'the list' anagrams to 'THISTLE'.
But, I'm not clear how the anagram is indicated.
'shows' acts as a link.
Can you help me to learn more?
(Other definitions for thistle that I've seen before include "The list includes Scottish emblem" , "Prickly plant (Carduus)" , "Scottish flower" , "Prickly weed" , "Scottish national emblem" .)
