Langdi was a script commonly used by traders used to write Haryanvi, Punjabi, or Saraiki in the Indian subcontinent .^[1] Bookkeepers, known as munīm (Hindi: मुनीम, Urdu: مُنیم), would also keep records in this script.^[1]

Some scholars have claimed that Langdi is a form of Mahajani for writing in parts of Haryana. Its proper connection must be more thoroughly explored.^[2]
