Church musician giving up time for European run (8)
I believe the answer is:
organise
'run' is the definition.
(run can mean to organise or control something)
'church musician giving up time for european' is the wordplay.
'church musician' becomes 'organist' (I've seen this in another clue).
'giving up' indicates named letters should be taken away.
'time' becomes 't' (abbreviation).
'for european' becomes 'e' (I can't explain this - if you can you should give a lot more credence to this answer).
'organist' with 't' taken out is 'organis'.
'organis'+'e'='ORGANISE'
Can you help me to learn more?
(Other definitions for organise that I've seen before include "Arrange in a systematic or orderly way" , "Onagers I manage to make arrangements for" , "run" , "Catalogue" , "Arrange, plan or direct" .)
