Article added to champion Scot's memorabilia (10)
I believe the answer is:
victoriana
'memorabilia' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'article added to champion scot's' is the wordplay.
'article' becomes 'a' (indefinite article).
'added to' is a charade indicator (letters next to each other).
'champion' becomes 'victor' (I've seen this before**).
'scot' becomes 'ian'.
'victor'+'ian'='victorian'
'a' after 'victorian' is 'VICTORIANA'.
Can you help me to learn more?
(Another definition for victoriana that I've seen is " 1837-1901 bric-a-brac".)
