Urdu
The letters in Urdu are derived from the Persian/Farsi alphabet, which is derived from the Arabic alphabet. The additional letters that are found in Urdu include ٹ ,ڈ ,ڑ (ṫ, ḋ, ṙ). To make the alphabet more enriched, two letters were created for the sounds ه (h) and ی (y). By adding these letters to the existing Persian letters, the Urdu alphabet became more suitable for the people of Pakistan and for some people of North India, who primarily use nastaliq script. Both are also Indo-Iranic languages descending from Proto-Indo-Iranic, but deriving from separate subbranches, Iranic and Indo-Aryan respectively.
