Siraiki is an old language of Indus valley ,now spoken in centeral Pakistan.It is presumed that this language is an Indo-iranian language related with Aryan languages family .It is idea of the English Linguists. I think it is not correct .Siraiki is oldest than Aryan languages .When Aryan reached in this area several Dravidian and Munda languages were being spoken here.
When we study about vocabulary of Siraiki language ,we find sixty percent words of Dravidians and Munda languages in Siraiki language .Besides it phonetic system of Siraiki language is different form Aryan language.
Perhaps you know that now several linguists of Pakistan are admitting this idea like Ain-ul-Haq Faridkoti etc
This Area (Centeral Pakistan) is the place of south Asia where history started its journy.When man reached here from East Africa,he was speaking the earliest language of human beings and it is the origin of Proto-Siraiki(PS)
It is admitted fact that man started cultivation in this area on the bank of Sindhu,and till earliest words about cultivation are with same sounds in Siraiki language like Hala(Mandari) and Hal in Siraiki
Several caste of Munda tribes like KHOL are living in Siraiki and Sindhi lands with the same name of Kehal
First city of this area is JalilPur inDistrict Khanewal. It is oldest city than Harappa and Moenjodaro.
Therefore i may say that Siraiki language and civilization are the oldest language and civilization of the world ,and concept of Indo-Iranian about Siraiki is not correct
