European throws glance at English style (8)
I believe the answer is:
elegance
'style' is the definition.
(thesaurus)
'european throws glance at english' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'throws' indicates an anagram.
'at' means one lot of letters go next to another.
'english' becomes 'e' (abbreviation).
'glance' anagrammed gives 'leganc'.
'e'+'leganc'+'e'='ELEGANCE'
(Other definitions for elegance that I've seen before include "Refinement - grace" , "Fine quality" , "Style; refinement" , "Refinement in taste and dress" , "Gracefulness" .)
