Explanation:

The Indoic or Indica languages are a subgroup of languages, belonging to the Indo-Iranian group of the Indo-European languages. They are spoken in the countries of the Indian subcontinent.

In the second millennium a. C. the Indo-Aryan was spoken in the center and north of the Indian subcontinent, especially in the basins of the Indus and the Ganges, but also by the elite of the State of Mitanni (currently northern Syria and Iraq). Historically, the Indian subcontinent was the main region of development of this group of languages. However, culturally these languages were influential throughout South Asia.

Towards the first millennium d. Sanskrit was also used for private purposes in Southeast Asia and western Indonesia, where it remained important until the Islamization of the region. In fact, the languages of Southeast Asia developed systems of scriptures inspired by the Sanskrit system and took many cultisms and lexical borrowings from Sanskrit. The expansion of Buddhism in Central Asia and the Far East also brought the influence of Sanskrit to these regions. For example, the typical order of the Japanese kanas is clearly inspired by the order of the Devanagari alphabet of Sanskrit.
