Finnish port one from Ankara found acceptable (5)

I believe the answer is:

turku

'finnish port' is the definition.
(port in Finland)

'one from ankara found acceptable' is the wordplay.
'one from ankara' becomes 'Turk' (Ankara is the capital of Turkey).
'found' means one lot of letters go next to another.
'acceptable' becomes 'u' (as in U and non-U speech).
'turk'+'u'='TURKU'

(Another definition for turku that I've seen is " town in Finland".)
