Festive icon's way in from Northern Europe (6)
I believe the answer is:
nordic
'northern europe' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'festive icon's way in' is the wordplay.
'festive' becomes 'rd' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'way' indicates an anagram (another way of arranging the letters).
'in' indicates putting letters inside.
'icon' with letters rearranged gives 'noic'.
'rd' going into 'noic' is 'NORDIC'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for nordic that I've seen before include "Relating to a people of Scandinavia" , "required tall and blonde" , "People of Northern Europe" , "Relating to Scandinavian language" , "Relating to Germanic people of N Europe, tall and blonde" .)
