Language
Spoken language is just one type of language, which has been defined in many different ways across history.
Hindi and Urdu are mutually intelligible in speech because they share the same Indo-Aryan base, grammar, and phonology, having both evolved from the Khari Boli dialect.123
Their divergence into distinct literary and written traditions is primarily a result of historical, religious, and political factors rather than linguistic ones:
- Lexical Differences: During the standardization process in the 19th century, Hindi increasingly drew from Sanskrit for its formal vocabulary, while Urdu drew heavily from Persian and Arabic.13
- Writing Systems: The most visible distinction is the script. Urdu is written in the Nastaliq (a modified Perso-Arabic) script, whereas Hindi is written in Devanagari.12
- Sociopolitical Factors: The partition of the Indian subcontinent solidified these differences, as the two languages became official state symbols for India and Pakistan, respectively.3
While they are often treated as independent languages due to these literary and scriptural differences, they remain functionally similar in everyday vernacular communication.123
