Test player on European anthem (14)
I believe the answer is:
internationale
'anthem' is the definition.
(Internationale is an example)
'test player on european' is the wordplay.
I cannot really see how this works, but
'player' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
'on' could be 'at' (I've seen this in other clues) and 'at' is found in the answer.
'european' could be 'e' (abbreviation e.g. EU) and 'e' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for internationale that I've seen before include "Left to play this" , "revolutionary hymn" , "Socialist's revolutionary song" .)
