Tamil

Sangam literature, the earliest substantial body of Tamil writing, dates to roughly the 3rd century BCE through the 3rd century CE. Tamil is one of the few languages with a continuous, recognized classical canon spanning more than two millennia, and it was officially declared a 'Classical Language' by the Indian government in 2004 — the first Indian language to receive that designation.

Literary Tamil (centamiḻ) and spoken Tamil (koccaitamiḻ) differ in vocabulary, grammar endings, and even some pronouns. Books, news, and formal speeches use the literary register; conversation, film, and informal writing use spoken Tamil. Speakers move between them fluidly, but learners often hit a wall when course material in one register doesn't match real conversation in the other.

Primarily in the Indian state of Tamil Nadu (~70 million speakers), in Sri Lanka (mostly the north and east, ~3 million), and in Singapore and Malaysia. Significant diaspora communities exist in the United Kingdom, Canada, the United States, Australia, and Mauritius. Tamil also has substantial heritage communities across Réunion, Fiji, and South Africa.

No. Tamil is Dravidian; Sanskrit is Indo-European. The two language families have been in contact for thousands of years and Tamil has borrowed Sanskrit vocabulary at higher registers, but the underlying grammar and core vocabulary are independently developed. Tamil has actively resisted heavy Sanskritization in modern times more than other Dravidian languages have.

Among the harder major languages. The script takes a couple of weeks. The grammar is agglutinative with long suffix chains and case marking that has no English parallel. Diglossia adds friction. Vocabulary is largely Dravidian with little overlap with English. Most learners reach reading literacy faster than conversational fluency, partly because of the diglossic split.
