English friend upset being cultured? (7)
I believe the answer is:
refined
'cultured?' is the definition.
(synonyms)
'english friend upset' is the wordplay.
'english' becomes 'E' (abbreviation).
'upset' indicates anagramming the letters.
'e'+'friend'='efriend'
'efriend' is an anagram of 'REFINED'.
'being' is the link.
(Other definitions for refined that I've seen before include "Polished" , "Urbane" , "Elegant, cultured" , "With impurities removed" , "Not coarse" .)
