Plastic raincoat from the Balkans (8)
I believe the answer is:
croatian
'from the balkans' is the definition.
I can't tell whether this definition defines the answer.
'plastic raincoat' is the wordplay.
'plastic' indicates anagramming the letters (plastic can mean easily moulded).
'raincoat' anagrammed gives 'CROATIAN'.
Can you help me to learn more?
(Other definitions for croatian that I've seen before include "Raincoat (anag.)" , "Slavic language" , "from area in Europe" , "Native to a Balkan republic that became independent in 1991" , "European native" .)
