Translation from a Carib language (6)
I believe the answer is:
arabic
'language' is the definition.
(Arabic is a language)
'translation from a carib' is the wordplay.
'translation from' is an anagram indicator.
'a'+'carib'='acarib'
'acarib' is an anagram of 'ARABIC'.
(Other definitions for arabic that I've seen before include "CIA bar on this Middle East language" , "Major language of Middle East" , "Like numerals one, two, three etc." , "Common language of Middle East" , "Official language of Egypt" .)
