This research paper is an analytical study of the ancient language spoken mainly in South Punjab which is now recognized as Saraiki. While Saraiki has been spoken in Central Punjab under several names in the past and has been closely associated with other regional languages i.e. Sindhi and Punjabi.The common assumption is that this language has been spoken since the earliest days of Sindhi civilization.In this Saraiki-speaking region, people of different ethnic groups have migrated and settled here. After settling in this region, Saraiki language was made as a lingua franca. One of the reasons Saraiki was promoted as a language of communication was its economic and commercial language in the region. The main reason was to interact with the local people. Where the locals were unfamiliar with the language of the migrants, the immigrants had to resort to agribusiness, interaction and communication. Apart from the evolution of Saraiki, it developed a connection with other languages due to Judges. This research paper explains the orthodoxy of Saraiki language and its relation to other regional languages especially Sindhi and Punjabi as well as an economic based language.
