King -- Urdu not quite his original language (7)
I believe the answer is:
kurdish
'language' is the definition.
(Kurdish is an example)
'king urdu not quite his original' is the wordplay.
'king' becomes 'k'.
'not quite' means to remove the last letter.
'original' is an anagram indicator.
'urdu' with its last letter taken off is 'urd'.
'his' with letters rearranged gives 'ish'.
'k'+'urd'+'ish'='KURDISH'
(Other definitions for kurdish that I've seen before include "Foreign tongue" , "Iranian language spoken also in Turkey, Iraq and Syria" , "Middle-Eastern language" , "Of a Middle Eastern people" .)
