The oldest script of India is known as 'Indus script' or Indus script. The symbols of this script are imprinted on many seals which have been found from the ruins of Harappa and Mohenjodaro. This script is as controversial as it is important. More or less all its aspects are entangled. It is given the name Indus script only for the convenience of description. To what extent such naming is appropriate cannot be said with certainty. Generally this script is given this name. Pointing towards the significance of the given name, Dani says that although this script did not actually originate in the Indus valley, yet this script was mainly used in this region. But this statement of Dani seems bold. It does not seem relevant to raise the question of origin here. Until supporting evidence is found in favor or against, no suggestion can be made on the basis of this. Apart from this, it also seems disturbing that its main usage area was the Indus region. The signs of this script found in the excavation of Kalibangan make it possible that this script was not limited to the Indus region only. In fact, the correct naming of a script is based on the structure and form of its inscriptions. According to the predominance of religious, commercial or secular elements, the script is given a corresponding name. For example, the names of the Hieroglyphic, Hieratic and Demotic scripts prevalent in Egypt have been decided keeping these elements in mind. Therefore, it is necessary to note that a name like Indus script is not meaningful. Until the structure of its inscriptions is decided, the name proposed and used for it cannot be recognized as final. Till now all the efforts made to read the Indus script have not been able to proceed beyond the primary level. Therefore, in such a situation, a name like Indus script can be considered only a matter of convenience.
