Marianne's appalling language (8)

I believe the answer is:

armenian

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for armenian that I've seen before include "language" , "Person from Yerevan, say" , "Eg, native of Yerevan" , "ethnic group in Asia" , "of the Southern Caucasus" .)

I've seen this clue in The Sun.
