EU anthem played across a place of learning (9)
I believe the answer is:
athenaeum
'of learning' is the definition.
The definition suggests a singular noun which matches the answer.
'eu anthem played across a' is the wordplay.
'played' indicates an anagram (letters playing around).
'across' is an insertion indicator.
'eu'+'anthem'='euanthem'
'euanthem' anagrammed gives 'atheneum'.
'atheneum' placed around 'a' is 'ATHENAEUM'.
'place' acts as a link.
Can you help me to learn more?
(Another definition for athenaeum that I've seen is " London club for the learned".)
