Language heard from Cockney Liverpudlian Bob? (4)
I believe the answer is:
urdu
'language' is the definition.
(Urdu is an example)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(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" .)
