Sant Bhasha (Sant Bhāṣā) is an esperanto-like language, composed of vocabulary common to North Indian languages, which was extensively used by saints and poets to compose religious verses. It can be understood by readers with a background in either Punjabi, Hindi or Urdu.
Apart from Punjabi and Hindi dialects, Sant Bhasha contains words from Sanskrit, Prakrit, Apabhramsha, Persian and Arabic. It is most prominently used in the Sikh holy book, the Guru Granth Sahib. The languages used include Lehndi dialect of Punjabi, regional Prakrits, Apabhramsa, Sanskrit, Hindi languages (Brajbhasha, Old Hindi, Awadhi etc.), Sindhi, and Persian.

"Remarkably, neither is the Qur'an written in Urdu language, nor are the Hindu scriptures written in Hindi, whereas the compositions in the Sikh holy scripture, Adi Granth, are a melange of various dialects, often coalesced under the generic title of Sant Bhasha."

But the broad range of contributors to the text produced a complex mix of regional dialects."

"Any attempt at translating songs from the Adi Granth certainly involves working not with one language, but several, along with dialectical differences. The languages used by the saints range from Sanskrit; regional Prakrits; western, eastern and southern Apabhramsa; and Sahaskrit. More particularly, we find sant bhasha, Marathi, Old Hindi, central and Lehndi Panjabi, Sindhi and Persian. There are also many dialects deployed, such as Purbi Marwari, Bangru, Dakhni, Malwai, and Awadhi."
