The morphology of word formation is unique and of its own kind where a word is formed from a tiny seed root (called dhatu) in a precise grammatical order which has been the same since the very beginning.
Any number of desired words could be created through its root words and the prefix and suffix system as detailed in the Ashtadhyayi of Panini.
90 forms of each verb and 21 forms of each noun or pronoun could be formed that could be used in any situation.
The perfect form of the Vedic Sanskrit language had already existed thousands of years earlier even before the infancy of the earliest prime languages of the world like Greek, Hebrew and Latin etc.
The Sanskrit word matri, with a long ‘a’ and soft ‘t,’ became mater in Greek and mother in English(effect of unqualified people, passing by word of mouth, through generations, traveling to the other part of the world).
Since the beginning there was a complete dictionary of root words called dhatu that could create any number of words based on the requirement by adding a proper prefix and suffix described in detail in the Sanskrit grammar.
Such apbhranshas of Sanskrit words are found in all the languages of the world and this situation itself proves that Sanskrit was the mother language of the world.
