European accepts amateur line judges in sport (10,5)
I believe the answer is:
australian rules
'sport' is the definition.
(I've seen this before)
'european accepts amateur line judges' is the wordplay.
I cannot really understand how this works, but
'european' could be 'e' (abbreviation e.g. EU) and 'e' is found in the answer.
'amateur' could be 'l' (as in a learner driver with L-plates on their car) and 'l' is found in the answer.
'line' could be 'l' (used when specifying particular lines from a poem) and 'l' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for australian rules that I've seen before include "sport" , "game" , "football" , "Sporting activity" .)
