Teenager Nick translated classical language (7,5)

I believe the answer is:

ancient greek

'classical language' is the definition.
(I've seen this before)

'teenager nick translated' is the wordplay.
'translated' is an anagram indicator.
'teenager'+'nick'='teenagernick'
'teenagernick' is an anagram of 'ANCIENT GREEK'.

(Another definition for ancient greek that I've seen is " Classical language".)

I've seen this clue in The Everyman puzzle in The Observer.
