Trained actor is acting initially somewhere in Europe
I believe the answer is:
croatia
'somewhere in europe' is the definition.
(European nation)
'trained actor is acting initially' is the wordplay.
'trained' is an anagram indicator (to train can mean to grow something into a shape).
'initially' says to take the initial letters.
The initial letters of 'is acting' is 'ia'.
'actor' anagrammed gives 'croat'.
'croat'+'ia'='CROATIA'
(Other definitions for croatia that I've seen before include "From small country" , "Balkan country, capital Zagreb" , "Adriatic country" , "Adriatic nation" , "Balkan state, became independent in 1991" .)
