Kannada

Mostly in the Indian state of Karnataka (around 38 million native speakers), with sizeable communities in adjacent regions of Maharashtra, Andhra Pradesh, Tamil Nadu, and Kerala. Bangalore (Bengaluru) is the largest Kannada-speaking city, though the city's tech-driven population growth has shifted its day-to-day linguistic mix toward English and Hindi alongside Kannada.

Both are Dravidian and use closely related scripts that look almost identical at a casual glance, with similar rounded shapes. Kannada and Telugu share grammatical structure (agglutinative, eight cases, SOV order) and many cognates, but they're separate languages and not fully mutually intelligible. The two scripts diverged from a common ancestor about a thousand years ago and now belong to neighbouring states.

Substantial. Kannada has continuous literature from at least the 9th century, with the Kavirajamarga the earliest surviving major work, plus Jain religious texts, Vachana poetry of the 12th-century Lingayat reform movement, and ongoing modern literature with eight Jnanpith Award winners — the most for any Indian language tied with Hindi. The classical Kannada of inscriptions reads quite differently from modern spoken Kannada.

Yes — three honorific levels show up in pronouns and verb forms: a familiar/intimate form, a polite/neutral form, and a more formal-respectful form. Verb endings encode the level, and using the wrong one can sound disrespectful or oddly distant. Modern colloquial speech tends to be less formal than classical literary Kannada.

The script is learnable in two to three weeks. The grammar is agglutinative — long suffix chains on nouns and verbs — which feels different from English but follows regular patterns. Vocabulary is largely Dravidian with substantial Sanskrit borrowing at higher registers and growing English loanword use in urban speech. The genuinely difficult parts are the verb conjugation system and consistent gender-number-honorific agreement.
