Turn out European winner, having no alternative (5)
I believe the answer is:
evict
'turn' is the definition.
(thesaurus)
'out european winner having no alternative' is the wordplay.
'out european' becomes 'e' (abbreviation e.g. EU. I am not sure about the 'out' bit.).
'winner' becomes 'victor' (synonyms).
'having no' indicates named letters should be taken away.
'alternative' becomes 'or'.
'victor' with 'or' taken out is 'vict'.
'e'+'vict'='EVICT'
Can you help me to learn more?
(Other definitions for evict that I've seen before include "Throw out of property" , "Remove form house for non-payment" , "Throw out, expel" , "Turn out (of property)" , "Force to move out" .)
