Language heard from Cockney Liverpudlian Bob? (4)

I believe the answer is:

urdu

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

'language' is the definition.
(Urdu is an example)

I don't understand how the rest of the clue works.

(Other definitions for urdu that I've seen before include "Official language used in Pakistan" , "speech" , "An official language of Pakistan related to Hindi" , "Indian language" , "One of official languages of Pakistan" .)

I've seen this clue in The Telegraph.
