Tamil is a Dravidian language spoken mainly in Southern India, Sri Lanka, Singapore and Malaysia, being an official language to all but the latter. It is an agglutinative language, making it sound absolutely awesome and like the speaker's mouth is on fire. As Russell Peters once said (well not word for word) "You can tell if an Indian speaking English is Tamil, cause when they speak, they forget they're speaking English and think they're speaking Tamil so it sounds like this" (he makes an impression of incredibly fast speaking which cracks up the audience).

It also must be noted that Tamil is much better then any other Indian language (including Sinhala), and looks completely different to them all.
