One of the major differences between the South and the rest of India are the languages spoken. The four major languages, Kannada in Karnataka, Malayalam in Kerala, Tamil in Tamil Nadu and Telugu in Andhra Pradesh are all Dravidian languages entirely unrelated to the Indo-Aryan languages, such as Hindi, spoken in the rest of the country, though they contain many loan words from Sanskrit. Even the scripts of all four languages, while originally Indic, have diverged quite radically from Devanagari.
As a rule, throughout the South, English is better understood than Hindi. The Tamils, in particular, have resented Delhi's occasional attempts to impose Hindi on them, and many will find it offensive if you try to talk to them in Hindi. Learning a few words of the local lingo, on the other hand, will go down a treat. Outside Tamil Nadu, Hindi is still usable as all educated people will have learnt Hindi in school, though it is not widely spoken in rural areas.
