Turn out for Louis I in European court (5)
I believe the answer is:
eject
'turn out' is the definition.
(I know this)
'louis i in european court' is the wordplay.
'louis i' becomes 'je' (I can't explain this - if you can you should believe this answer much more).
'in' is an insertion indicator.
'european' becomes 'E' (abbreviation e.g. EU).
'court' becomes 'ct' (abbreviation used in road names).
'e'+'ct'='ect'
'je' inserted within 'ect' is 'EJECT'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for eject that I've seen before include "Throw out violently" , "Boot out" , "Send out forcibly" , "Discharge; evacuate" , "Turf out" .)
