There is a conflicting opinion about the language of the Indus script. Some linguists believe it was based on the Indo-European language; another group claims it was based on the Dravidian language. My findings indicate that the Indus script was a composite language, comprising elements of the Indo-European (IE) language and Egyptian hieroglyphics. I refer to the influence of hieroglyphics as a Dravidian component. My decipherment effort so far indicates that many Indus symbols resemble Egyptian hieroglyphs, and that there is a close connection between the two writing systems. The Egyptian priests and scribes likely contributed to the development of the Indus script, along with Iranian and Vedic priests. The Indus symbols show a composite culture of all three great civilisations. This paper argues for a moderate interpretation of Sanskrit influence within a hybrid cultural context.
