How has the Sanskrit language spread?
Sanskrit or संस्कृतम्, saṃskṛtam, a classical language of South Asia, that connotes several Old Indo-Aryan varieties, is a sacred language of Hinduism, the language of classical Hindu philosophy, and language of historical texts of Buddhism and Jainism.
“Sanskrit” can also more narrowly refer to Classical Sanskrit, a refined and standardized grammatical form that emerged in the mid-1st millennium BCE and was codified in the most comprehensive of ancient grammars, the Aṣṭādhyāyī (“Eight Chapters”) written and composed by Pāṇini ( पाणिनि, a Sanskrit philologist, grammarian, and revered scholar in ancient who finds a mention between the 6th and 4th century BCE, also considered the “first descriptive linguist”, and even labelled as “the father of linguistics since the discovery and publication of his work by European scholars in the nineteenth century).
The greatest dramatist in Sanskrit Kālidāsa wrote in classical Sanskrit, and the foundations of modern arithmetic were first described in classical Sanskrit. The two major Sanskrit epics, the Mahābhārata and the Rāmāyaṇa, however, were composed in a range of oral storytelling registers called Epic Sanskrit which was used in northern India between 400 BCE and 300 CE, and roughly contemporary with classical Sanskrit.
In the following centuries, Sanskrit became tradition-bound, stopped being learned as a first language, and ultimately stopped developing as a living language.
The hymns of the Rigveda are notably similar to the most archaic poems of the Iranian and Greek language families, the Gathas of old Avestan and the Iliad of Homer. As the Rigveda was orally transmitted by methods of memorisation of exceptional complexity, rigour and fidelity, as a single text without variant readings, its preserved archaic syntax and morphology are of vital importance in the reconstruction of the common ancestor language Proto-Indo-European. Sanskrit does not have an attested native script: from around the turn of the 1st-millennium CE, it has been written in various Brahmic scripts, and in the modern era most commonly in Devanagari.
