What does the word “Urdu” literally mean?

The word "Urdu" literally means "camp" in Turkish, reflecting its origins as the language that developed in military camps (zaban-e-urdu-e-mualla) during the Delhi Sultanate period. Soldiers and merchants from different linguistic backgrounds (Persian, Turkish, Arabic, and local Indian languages) communicating in these camps created this hybrid language. The term captures Urdu's emergence from the mixing of diverse linguistic groups in marketplaces and military encampments.
